My muse and I are unusually impatient, so I'll just post this and start the next update operating under the assumption Jade will be staying in Magnostadt. Voting is not locked and can be flipped to "leave." Either way, this is what Jade will see in place of Avatar when she next visits Eternity.
A world of White, and... honestly, it's a weird one. Aliens — and not of the human variety — seem to have conquered this Earth some few decades before, instituting a global government known as the ADVENT Coalition. Despite their rather dubious methods of initially asserting control, they actually seem to have been doing a pretty good job — mostly. The alien spiritual (and effective) leaders, the Elders, seem to be outright dead. The Elders are, of course, refusing to properly acknowledge this fact and are doing everything they can to prevent their proper passage onward. As expected, their continued efforts to cling to (un?)life have rewarded mixed results. Their mastery of soul magic may let them offload the damage of transfer onto the bodies they migrate into rather than doing further damage to their own souls, but dodging said damage leaves their vessels as withered, dying husks.
Unfortunately for the human race, these transfers mean taking human vessels. The Elders do, to their credit, seem to be working on a more permanent solution, but in the meantime, they basically require sacrifices of some two thousand humans every single week. Oh, they hide the disappearances under the guise of permanent military service with invasive adjustments, terrorist attacks, or "leaving the cities on relief missions," but you can see where their victims are actually going. The soldiers allegedly join the faceless masses of genetically modified soldiers and the volunteers are "killed by dissidents."
Fortunately for your state of mind, the Elders aren't operating unopposed. A rebel (or possibly terrorist if you believe ADVENT) group known as XCOM (Extraterrestrial Combat Unit) is doing their utmost to not only violently oppose the alien threat, but also learn from their technologies and mastery of soul magic. You can't tell if the Elders are leaving XCOM alive simply so they have high-profile scapegoats or if XCOM is genuinely competent enough to avoid destruction. Either way, XCOM honestly doesn't seem to be accomplishing all that much in the way of solid victories. Ones good for morale, sure, but they haven't done real damage since they lost the support of Earth's old governments two decades ago.
You think Mom might actually want you to visit this plane, albeit maybe without all your friends. You wouldn't have technological superiority there, only the results of a separate technological path. Although their path looks like one of the ones that ends in self-destruction, you can steal the stones from their road to improve your own.
However, it doesn't look as though you'll be able to just waltz into an ADVENT city and grab anything shiny. Identity scanners are as common as lightposts and obtaining ID requires, among other things, a brain implant. Or the implant might be the ID. It's hard to tell, honestly. It's a good thing much of the human race still lives outside ADVENT's cities; them, you'll be able to roam freely among. Well, mostly. Some rather unpleasant groups have formed in the absence of governments to stop them. XCOM does support order in some areas, but only in Europe and northern Africa. Their efforts to expand further are ongoing.
There are also six other major resistance factions, albeit ones which aren't as individually powerful as XCOM — which is a bit sad, actually, since XCOM isn't doing too well either. Anyway, the Templar are soul mages willing to embrace madness and other assorted side effects in the name of unlocking further power, EXALT is obsessed with general improvement of human bodies and views the Elders as selfishly interfering, the Skirmishers are those few people who were modified for military service before managing to fight off the accompanying indoctrination, the Pilgrims spread resistance propaganda within ADVENT cities and help extract rebel sympathizers, the Council is a loose network of spies working within ADVENT while feeding information to the other groups, and the Reapers are expert scouts fond of sneaking in and blowing things up.
There's an irritatingly complicated web of who dislikes who, too, which mostly seems caused by their tendency to trip over one another. The fact that ADVENT can tear intelligence from the minds of their captives makes the various factions fear sharing operational details with the others, but in the absence of such? It isn't unheard of for Reapers to assassinate Councillors, Skirmishers to inadvertently draw attention to areas Pilgrims were canvassing, Templar to eliminate alien-modified humans EXALT wanted to study, and so on. You think it'll take you time to puzzle out the full web of likes and dislikes. The various factions are sometimes willing to put aside their differences for sufficiently large operations, but XCOM is usually used as an intermediary and the cooperation is always temporary.
If you want to be absolutely honest, you're not sure who or what you should be helping here, if anyone. The Elders are responsible for some genuinely horrifying atrocities, including ones which filled Earth's old cities with hordes of non-infectious zombies, but ADVENT is, for the most part, a successful post-scarcity society. If you can help the Elders sort out their whole undeath issue, they might create a genuine utopia.
...Well, maybe. The Elders do have a seven-member black ops group comprised of ludicrously enhanced former humans. You don't think their artificial vessels are better than yours, but they might be equal and the effective range of their Soul Obelisks(???) lets them maintain control across the continent they're stationed on. At any rate, this group is known as the Elder's Chosen, or Chosen for short. They're all religious fanatics, sociopaths, psychopaths, megalomaniacs, battle junkies, or some combination of the above, with individual kill counts in the hundreds or even thousands. You're not sure if their insanity is due to the slow soul degradation from their vessel swaps, which they seem to get about a dozen of, or if the Elders decided to upgrade a group of crazy people. Maybe both? Either way, they tend toward being rather territorial and don't team up even when their Obelisk-ranges overlap.
Most importantly, the Chosen have been promised personal rule over large swaths of Earth once the Elders sort out their whole death problem. You think the Hunter would turn his territory into some twisted human hunting reserve, the Missionary would cheerfully twist and rewrite the minds of her victims until they unknowingly reenact various stories, the Warlock would have much worse views on religion and respect than even Mom started with, the Scholar would perform all manner of gruesomely unethical experiments, the Seer would make personal freedom into a... wait, never mind, she died instantly after attacking the Elders or something. So make that six Chosen. Anyway, you have trouble looking at the Assassin and the shapeshifting Sleeper, so you're not sure what they'd do.
You can see that the Sleeper has already made it difficult for you to help XCOM; in Sleeper's early days, it posed as a humanoid (female) envoy from a star-spanning civilization willing to discreetly help XCOM as part of its cold war against the "Ethereals," the alleged true name of the Elders. The damage Sleeper did upon betraying them immediately reduced XCOM from seven bases to five, which soon dropped to four due to supply issues. Sleeper hasn't done anything quite so overtly damaging since then, but it does seem to extract particular delight from attacking XCOM recruitment drives. The various resistance factions may have melee-range (and for XCOM & EXALT, drone-mounted) scanners capable of detecting the nature of Sleeper, but they're exactly that: melee range. If Sleeper spots one of the scanners, it usually just tosses a plasma grenade at the closest group of sympathizers, shoots the scanner-wielder a few times, and runs like hell. At least the Sleeper has died a good seven or eight times so far, the highest out of any of the Chosen. Sadly, the resistance doesn't realize the Sleeper has a limited number of vessel swaps and views it as an undying bogeyman.
It doesn't help that the previously mentioned scanners seem to use the presence of a soul to determine whether a given person is the Sleeper in disguise. You think it could detect your Soul Gem if you were to show it to them, but they'd probably be shooting by then. XCOM and EXALT have even started designing their drones to immediately attack or outright detonate upon detecting someone without a soul. You can't even go to an outpost beyond the Sleeper's range since it is the only Chosen to appear all across the globe. Maybe because the other Chosen view it with scorn and don't view the Sleeper as a real competitor? You're still not sure how its Obelisk is supposed to move, though. It has to be a different design, you're sure of that much.
On a related note, XCOM is now down to two stationary bases, both of which are closer to supply depots (or expendable bait), and a flying command cruiser — the Avenger — stolen from the aliens, which is stealthed and most definitely not expendable. If the Avenger falls, XCOM would be left headless and helpless. This, more than anything else, makes you suspect the Elders are deliberately leaving them alive. XCOM was dismantled with brutal efficiency initially, but the Elders were stopped just short of the death blow? It just smells fishy to you.
Even before they got truly desperate, XCOM fell firmly among those believing the ends justify the means. They're not above using a combination of torture and mental deconstruction on human ADVENT officials in order to obtain information, to say nothing of what they do to captured aliens.
...Which ADVENT apparently does right back to them, or maybe even did first, but... ugh. You don't want to think too hard about this, but you suspect you will anyway. You can at least give them credit for not taking the easy way out and only calling it necessary; they're not above incorporating alien genetic modifications into volunteers with the assistance of nanomachines known as Meld. Not to the experimental extremes EXALT goes to, mind, but you still respect the courage involved there. If EXALT's means weren't even worse than XCOM's, you'd respect them, too; some of their volunteers replace their entire bodies from the neck down with robotic parts just so they can better fight ADVENT.
The mana levels of this third Earth are, for most of the world, rather abysmal, but you think it's worth noting that the Avenger somehow produces somewhere between four and eight motes. You're not sure why you'd be able to bond to it when the same doesn't hold true for your pendant. If it's a mana generator, why can you bond to it? And if it's a land, why can it move?
