FYI
Remaining Colony Options
Adrazzi Gulf (and adjacent) Sites
77 Azzadi IV-3 20 (40) SR/year
Located spin-corewards corner of -1f. (Well towards Federation side of Adrazzi Gulf.)
Description: Deposit of Icurium ores on the third moon of 77 Azzadi IV. Like at the Castor IV-2 vein, strong magma convection currents pull the ores towards the surface, then back down.
17 Onidesin IV, 20 (40) sr/year
Located -2g, tailwards.
Description: An exploitable vein of Woninium on 17 Onidesin IV, about half a kilometer under the planetary ocean's surface. A mining colony here would be only a modest technical challenge.
Galoria Delta-LXIg, 5 (9) rp per year.
Located in -4f, near Hajatar. (Near the Adrazzi Gulf, at Spinwards end of Straits of Themis.)
Description: This is a fascinating system [nearly three hundred separate planetoid or larger stellar bodies, of which at least one is a full M-class world, three are capable of supporting life and another five rate a solid .8 on the terraformability scale]. Just the stellar mechanics of its formation alone could keep an entire university department busy for the next sixty years, nevermind everything else [the atmosphere of Galoria Delta-LXIg contains a form of silicon based pseudo-prion capable of bypassing standard Starfleet filters].
(potentially) Politically Important Sites
Barradus IV 6 (10) rp/year)
Located in -2B. (On border between Vulcan sector and RBZ.)
Descripton: Inhabited by Bropal, a splinter Vulcan culture that have perfected mind-meld and katra-manipulating techniques that allow them to preserve the identities of the long dead in the form of...exchangeable personality fragments. They have an ancient computer backup facility that retains knowledge of the entire state of the Vulcans' known galaxy at the time of the exodus.
Analysis: The Vulcans really want this information, but can only get it when Starfleet builds the colony. Building it might even earn a little political goodwill or pp rebate.
LOL, So Far Away Sites
HKP-426, 7 (11) rp/year
Located coreward side of -8f. (Far beyond Federation borders rimwards, past Imelak territory and likely bordering the Ittick-ka.)
Description: Space around star is slides into parallel universe with exotic physics, not to mention exotic xenobiology in the form of the teleporting organisms.
Analysis: Neat, but not neat enough to support a research colony that far out and vulnerable to the Ittick-ka.
PLY-5000, 5(20) br/year
Located at H,7. (Coreward of Breen and far from Federation borders.)
Description: A giant asteroid made of gold.
Analysis: From update, "I realise that this site is so far from Federation borders that it's almost certainly going to be a liability to try to mine the remains of PLY-5000-Ia. Still, it's good to have this in the ol' memory banks for future reference or in case someone really wants gold for some reason!"
Everything Else
RVL-7836-VII 10 (30) sr/year
Located located at B5, 4ly tailwards of Canun.
Description: Analysing their geological report shows that RVL-7836-VII has ideal conditions for setting up a mining outpost that can siphon the molten magnesite to the surface through a series of force fields and then cooled for ease of transport.
Sarcissa Belt, 15 (30) BR/year
Located in bottom-left corner of -4f
Description: Tritanium deposits in planetary debris field (in Rethelia sector, near border with Cardassian-controlled Bajoran space).
Morgana-1321 rp Colony +5 (9) RP per month
Located at Coreward region of f,3 (In Gabriel expanse, coreward of currently claimed Federation territory.)
Description: Atemporal waves sweeping around the Star Morgana-1321, a small window to the end of the universe.
Analysis: Includes quantum filaments. Narratively cool, but as area is claimed for Federation by treaty the only real threat is the ISC claiming it first, and they'd take years to expand that far.
23 Levar VIII, 15 (35) SR/year
Located at e3 (just coreward of current Gabriel borders)
Description: Brospeh leeched valuable resources out of 23 Levar VIII, leaving it in an easily accessible ring around the planet.
Analysis: Pretty safe and just coreward of current Federation borders in Gabriel. Good choice for safe source of SR.
Falling Down (a-622), 20 (35) br/yr
Located in -6d. (Rimward edge of Rethelia sector.)
Description: A gas giant similar to Sol-V has a captive moon with an orbit that has decayed enough to bring it into the intense radiation belt of the gas giant. This charged the large tritanium deposits in the moon's crust. A mining colony in this location should either invest in heavier emitters or move the orbit of the moon permanently. It's relatively small mass would make this operation time consuming, but with mass-lightening bubbles and patience, it is plausible.
Analysis: Not the safest colony option ever, but it would be a nice forward position against Lecarre space.
CA-113, 15 (25) sr/yr
Located in upper right corner of 1c, near the Pure Intent research colony coreward of the Yrillians.
Description: The moon has been recombined, and is now more an irregular, glowing lump. Which means it's also irradiated in addition to being irregular. We've pulled back a bit, but I think if you set up a nice station and got some shielded workbees, this could be a pretty nice resource site.
Analysis: Well, it's near another colony and will made for a nice claim on that area of space if the Yrillians ever join the Federation.
LM-34-V-XL, b0, 20 (35) br/year
Located in b0. (Tellar sector, one of the safest places in the Federation these days.)
Description: Gas giant moon with a core of polysilicate verterium left from an impact with another asteroid.
Analysis: Nothing special other than it's a nice safe source of BR.
Aeneid III, (rimward of Betazed in Sol sector), 15 (35) sr/year
Located in b0. (Tellar sector, one of the safest places in the Federation these days.)
Description: M-Class planet that is stormy, turbulent, and has some pretty powerful background radiation, but is a beautiful earth-like planet, with the works: continents, oceans, a variety of biomes. The sun is throwing out a huge amount of heavy elements, made by a weird synthesis process. When these hit the Aeneid III magnetic field, they're getting trapped, and they like to collide with other captured debris. This makes the planet a natural source of Norvidium, something only ever found artificially and produced painstakingly in labs. Setting up some orbital habitats to start collecting this stuff would really make some warp plasma coolant manufacturers happy.
Analysis: Nicer source of SR in a safe part of space; might also have Major Colony potential.
Kr'ritti V, center of -5b, 15 (35) sr/year
Location: Located at center of -5b. (edge of Ferasa sector, bordering gap to Dawiar space
Description: The Kr'ritti system is one of the most astounding sights in the galaxy. The subspace storms actually have a locus here - a variety of exotic matter in the star's composition interacts with a stable subspace tear where the third planet used to be. There is some speculation that it was once inhabited, and lost during the age of the Tkon.
Great coruscating arcs of light shoot between planets in the system, some of which may have been terraformable in the distant past, but these days the radiation is just too strong. Only the fifth planet, a gas giant so large it was nearly a brown dwarf, is the electro-magnetic sheath strong enough to protect an installation. The interaction of these subspace energy bolts is generating a cornucopia of isotopes used in deflectors, EPS load balancers, and other purposes.
