Well ideally we'd have dry docks where we would build the initial portions of our base. The first portions of our base would be built like actual barge ships, four or five of them as the foundations of the village where we would lift it up from. We could also have an actual boat where we would have business conducted on the surface. Most boats would be large enough for our village to grow from during the set up phase. And living on the water gives us fish as a primary food source.
 
I really don't understand. How do we not insta-die when loyal Mist ninja find us? Are you saying that the only people who will be able to find us will be amiable to our situation and consequently the bad guys are all too incompetent to notice us for years at a time? Zabuza, the guy who slaughtered everyone else who defected from Mist, will be living there in addition to all of the other ANBU and other military police forces who regularly check for intruders. How do they not find us if we are living amongst the main population in disguise for all of those years? If we are powerful enough to infiltrate and not worry about Mist's forces (as in, our team vs. every loyal Ninja in Mist) why bother with subterfuge? We could rescue whomever we wanted to in a much shorter amount of time rather than deal with years of pretending to be academy students when we are all S rank.

Could you walk me through your thought process please? Maybe I'm missing something?
Basic idea:

-Sneak into Mist.
--This is not really viable long term, but it'll work for a while.
-Flip other nin.
--Find people who are sympathetic to our plight and/or we have diplomanced into sympathy and/or have beef with how Mist is currently run. Have them join the conspiracy. With them to help, we can maintain the illusion a little longer.
-Have a coup.
--We get rid of Yagura. Since he's the sticking point for a missing nin trying to reintegrate into Mist. With him gone and with us having gained significant political power in the process, we can join Mist again, above board.


This would be simplest, of course, if there is already discontent with Yagura.
 
I really like this idea, but honestly I think we can get something much more useful, and less prone to failure by inventing a reactionless thrust seal.

Place it on something, and it produces force in relation to some input parameter. (relative position of another control seal?)

That way we could just use PID controllers and overkill to make something that floats. It'd even be more resilient to various types of failures.

Yaaaaay PID controllers! I'm confused whether you mean "set up an in-atmosphere platform hovering on reaction less thrust seals", which I expect to have a significantly larger maintenance cost and be more prone to failure as it's subjected to varying atmospheric conditions, or if you're saying we should just skip living in the clouds and go straight to space?

Because that seems like a solid end goal, but we probably need to level our math skill quite a lot to make it viable. Or at least have shadow clones as disposable test pilots who can report back on our many trial runs :D
 
We don't need a flying village, we just need a Helicarrier. Mostly because a flying village needs some kind of food supply. Unless we can find air whales, or plant affinity people for ninja hydroponics.
 
-Sneak into Mist.
--This is not really viable long term, but it'll work for a while.

One of your proposals called for infiltrating the Academy to pose as students and then eventually graduate to be Mist ninja again.... if that's not long term, what is? Also, how long do you expect forming a coup d'etat to take? How many points in Deception do you think it will require?

-Flip other nin.
--Find people who are sympathetic to our plight and/or we have diplomanced into sympathy and/or have beef with how Mist is currently run. Have them join the conspiracy. With them to help, we can maintain the illusion a little longer.

How do we find them? How do we make sure they really do want to help us and aren't informants for Yagura? What do you think will be the necessary amount of Diplomacy to convince people to rebel?

-Have a coup.
--We get rid of Yagura. Since he's the sticking point for a missing nin trying to reintegrate into Mist. With him gone and with us having gained significant political power in the process, we can join Mist again, above board.

How many combat dice do you think we will need in order to beat Yagura and all of his loyalists? How do we convince everyone that Missing-nin aren't a blight on a ninja village? What do we do if other people want us dead simply because we are missing-nin?

How do you propose we get the whole team this strong to pull this off?

Without detailed answers I'm not inclined to pursue this course of action over other, to me, more interesting alternatives.

If we can make a seal that has an off and on switch (which I'm hesitant about because of the rules of Sealing way back when on the player knowledge doc) making a seal that points all of its explosive force in one direction would be amazing.

I'm not sure how we would control it since seals can't interact with other seals, but it has the potential to make spaceflight trivial.

Orbit also has the advantage of not requiring constant upkeep to maintain its general position. If we get high enough to necessitate environmental suits to wander outside of the complex and we are using the same propulsion systems as something capable of LEO or GEO, why not just go to space instead?

Space has asteroids we could mine with MEW and has orbital velocities to use for doomsday weapons. Furthermore, no ninjas that we know of have a spaceflight technique, but I'm sure there are plenty of ways for them to jump extremely high if not fly or glide long distances. Unless the state of math is higher than we anticipated, they also won't be able to hit a target in LEO easily, if at all. LEO also means that we could launch almost anywhere on the planet and with minimal fuss return to our station. A stationary platform floating in the sky would require longer travel times to get to.

I'm not saying a cloud city is a bad idea, in fact I'm ecstatic people are putting so much thought into it, I just don't see how it's better than an orbital station for a long term construction project. If we need practice with inventions, we could simply make zeppelins which would have the added benefit of being immediately useful for crossing borders effortlessly for trade or simply improved mobility.
 
Cloaking seals are a must to hide a sky base if we don't want people getting suspicious because of unusual clouds showing up. Two methods I can think of are making a seal that can apply henge to objects and making twin wall seals that take incoming light and project it from their partner. The henge seal has the downside of being static, so it would be noticeable against a changing background, but it would also protect the henged object from weak wear and tear. If the twin wall seal can project the light of the opposite wall from the same side that it's absorbing light, then we would also be camouflaged from above. Also, based on the diagram of the pieces that the structure would be built with I'm not sure if they already meet this criteria, but a design where there are always two 5BSed objects holding each other up for redundancy would be safer. Like the higher platform cradling the lower platform such that if the BS ran out on the lower one, it would still be held up, and the lower one would obviously hold up the higher one if it happened the other way around.
Honestly, with 6 months of R&D with Kagome, I suspect we could get this stuff sorted out pretty well.
 
We need an estimate of how much sealing we need to make this feasible.

Sealing 40 is "Destroy the planet for the lulz" and Sealing 10 is "Undergrad with No Experience", so we have pretty solid bounds on skill needed. We need more accurate bounds.

I was gonna say that they're currently designed this way, and then I realized that's not true at all and I have to go fix it.

Where's the sealing 40 figure from?
 
I'm too drunk to actually search, but I remember @eaglejarl posting a jokey omake about us destroying the world with sealing at Sealing 40.

Huh, in retrospect, I'm kinda drunk so Sealing 40 might not be so great an upper bound.

If it takes us Sealing 40 to destroy the world, I will be incredibly dissapointed in us all.

Hell, if it took us more than a slight modification of the seals we have right now to destroy the world, I would be incredibly dissapointed.
 
By what measure are you using the word "destroyed"?
The primary case I'm imagining right now is the "slight" modification of a barrier seal to NOT be immobile with respect to the earth and instead tear through it. Obviously that'd take a significant amount of doing, so it's not nearly so easy a thing as I make it out to be (for one thing it'd have to be able to withstand the force of the earth pushing against it).

You would also have to start it up on the correct side of the planet to not have it nope off into space without touching the planet
 
sphere of relatively airtight fabric 22m in diameter
  • This results in about 4*pi*222​ = 6082 m2​ surface area, enclosing 4/3*pi*223​=

Did you mean 44m diameter, or should those 22s be 11s? Surface area and volume use radius, not diameter.

Yeah! You could call it...I dunno, a 'shaped charge', maybe? ;>

That was @Jackercracks, and it was a joke with an indeterminate canonicity value.
 
...I wonder if we can weaponize barrier seals as a measure to bisect our opponents using the power of MATH.

e: Actually... we should look into seeing if Keiko's good enough at throwing weapons to throw two kunai at a sufficiently steady angle to apply a barrier seal between them.

I actually just found that!

It Rises. It Wakes.
Or: Sealing 40.
(Non-canon)
(you know, probably)

Across the breadth of time and space, through mountains and across oceans stretched a design beyond mortal knowing. The Seal was made in millennia and an instant. Beautiful and terrible, the ripples of its creation sung out to the time of the Sage and the Biju, setting in motion the events that would lead to the birth of its creator.

Sharingan-filtered it scarred the minds of an entire clan, warping and twisting their thoughts with insane plots and pointless vengeance. Byakygan-seen it brought panic and despair, and in their fear they caged their own kin in terror of what they might create, of what they might become. Rinnegan-glanced it shattered the mind like a sledgehammer through a glass monument, driving forth all reason and forcing a young god through an endless search to end the tortuous pain of existence.

On a grassy plain a figure smiled with razor lips as her works came into being. Sub-arrays stole chakra from the land in self-reinforcing cycles to create more and greater parts of the whole. Great segment-syllables scarred the land with fire and acid while sub-clauses shattered mountains to dust along precise geometric lines.

At once, all was still and ready. For a single perfect moment the entire world seemed to hold its breath.

Then the screaming began.

E: Fixed my fuckup


Long Term Project Proposal: Tengokugakure no Sato
"Village Hidden in the Heavens"

(Credit to @Cariyaga for the initial name idea and @MadScientist for producing a translation)​

I've been mulling over what it would take for us to establish a (semi-)permanent base in the sky. I'm dividing this project into two broad categories (stolen from @Logos):
  1. The creation of a vehicle or vehicles capable of moving to the desired height and returning to the surface (don't have to be the same vehicle)
  2. The establishment of a structure at the desired height which is capable of maintaining its height for an indefinite period.
Part 1: Vehicle Design and Manufacture
Most of the discussion on this point has centered on the construction of an airship or blimp based around the use of the Elemental Mastery technique Akane learned from Takahashi. The results are summarized here:





So it seems like this might really work. The main barriers to overcome appear to be:
  • Getting Akane to EM 8.
    • This will require 33 XP:
      • [*]Resolve 3 (0+6 = 6 XP)
        [*]Concentration 3 (6+6 = 12 XP)
        [*]EM 6 (12+6 = 18 XP)
        [*]EM 7 (18+7 = 25 XP)
        [*]EM 8 (25+8 = 33 XP)
    • Obviously this trades off against other things we want her to be able to do, such as boost her social and primary combat stats, but may be worth it if we are in a relatively secure situation and the rest of the plan is feasible.
  • Designing and producing the vehicle
    • Putting together the balloon portion of the airship will probably be the most difficult, requiring us to get our hands on a sphere of relatively airtight fabric 22m in diameter
      • This results in about 4*pi*112​ = 1520 m2​ surface area, enclosing 4/3*pi*113​=5575m3​, a little less than twice the most common size of hot air balloon according to Wikipedia and a little more than a quarter of the largest one I was able to find with a cursory Google search. If this proves prohibitively large, Akane can go up to EM 9 for just 9 more XP (total of 42) because of how the attribute caps are structured, which will help some.
      • A point about air-tightness: apparently the best practice for hot air balloons is to use something called a French fell stitch:
      • As far as material: supple leather? Supposedly cotton works? Do we need to invent nylon? Picking a material and getting enough of it will be one of the major challenges, since the raw labor problem can be ameliorated with clones.
      • Modern day hot air balloons have vents to control how much hot air is kept in the balloon so the pilot can control rate of ascent and descent. With a combination of EM and storage-scroll ballasts, we probably won't need to worry about this.
    • Putting together the carriage for passengers seems pretty trivial relative to the above - basically make a nice little wooden structure we can secure to the floatation component
      • However, there needs to be sufficient structural support throughout the contraption that it will not tear at the points where the carriage is attached
    • Could be a nice joint project for Kei and Akane to work on their relationship, combining Akane's mechancal aptitude with Keiko's bloodline to pull off some cool engineering and testing, with everyone contributing clones to help in the building process
@MadScientist has also suggested an alternative route using MEW to lift up a chamber of stone to sufficient height which hasn't been explored as fully, but which may make the second step easier.

2. ALL OUR BASE ARE BELONG TO US

Once we can get up high enough to be safe from pretty much whatever people on the ground want to throw at us (I don't recall anyone with the ability to throw jutsu 2 kilometers), we can start putting together a structure up there, since just having Akane constantly keep our airship afloat is obviously unsustainable.

Kagome has told us that the Five-Seal Barrier locks a sealed object of limited volume in place w.r.t. the earth and makes it indestructible for up to a month if none of the tags supporting it are damaged or moved.


My first thought was to make use of the maximum volume limiter and bring up a bunch of fishing nets with us to act as the foundations for our base, but I assume the fibers in those will count as part of a larger object to prevent us from truly absurd levels of munchkinry.

Instead, let's use a series of interlocking solid structures that support one another. My current idea is to have solid stone crosses with arms long enough that the support seals for 5SB can be placed on them to hold the whole thing immutable. I *think* Hazou can produce these using MEW, or if not can get better at MEW and do so. The limiting factor on arm length is going to be the mass we're able to transport, but it has to be at least 3m for 5SB to work.



E2: Thanks @1234qwerty for making me aware of this issue. The system as described above can only be extended along a single axis, since joining a new piece takes up two adjacent arms. The resulting platform would just look like this: XXXXXXXX

To be able to make a broad platform, I think you need to include a second set of crosses with cutouts halfway up the arms. these serve as crosslinks between the long chains. I'm pretty sure this also means that the arms of the originals have to be slightly lengthened so the crosslinkers can have slightly shorter arms that don't collide with other links, since the minimum arm length is still 3m.


If we can inscribe seals directly onto the crosses rather than relying on paper that might blow away, that may be a better option. The weird specification about where the cutouts go is to make sure that there aren't any crosses that will just fall out from under the structure if their seals fail, which would happen if we went the alternative route of having half of the crosses with all their cutouts up and half with them all down. You could also do 180 degree separation but that requires twisting crosses into place during construction rather than sliding them, so I'm not sure the geometry works out but if it did it would be even more secure during seal failure.

After the first couple crosses are in place as a stable platform, use either summoner blood exploit, massive storage scrolls, cheeky use of MEW, or repeated airship trips to transport or produce lots more up there. Once a framework is established we can throw nets or floorboards between the holes. Go through and refresh seals every couple weeks on a rotating schedule, so that there are always some fresh ones holding the whole thing up.

If this were to get turned into an actual hidden village, there should be places throughout the area with hot air balloons in case of emergency, and every child with enough chakra should be taught EM early so they can maybe help the hot air balloon they're in crash slightly less during an evacuation. We should also consider teaching a disproportionately large number of inhabitants enough sealing to allow them to maintain the system.

Questions to be answered:
  • What kinds of fabrics exist in the elemental nations?
  • Can someone with a summoner's blood and a summons' consent perform summoning?
    • If so, how much mass can a summons bring back with it to their realm/into our realm?
  • What's the biggest thing we can fit in a storage scroll using Hazou and Kagome's current abilities? Can we potentialy research a larger one?
    • Even better obviously would be to Hiraishin them up but that seems like a bigger project.
  • How much earth has to be around for the nonconservation thing to work for MEW? (i.e. if we haul up a rock slab, can we just make more rock when we're up there)
E1: Initial quick calculation: as an example, granite has a density around 2750 kg/m3​. At a height of 2km in my estimates above, we have about 1500 excess newtons of lift. That means we can haul up 0.054 m3​ of granite. Modeling a cross as two rectangular prisms, the sturdiest one we can haul up at one time is about 6m*6cm*7cm. We could improve that by taking up less people and gear on construction trips, or by improving Akane's EM to 9.

Let me know what you all think!
