So, eventually, BfA will end, as all expansions end, and we’ll get another chance at trying to figure out what to do now that we’re not trying to massacre each other.
What is your character going to do?
It’s very likely that it’ll end in another contrived stalemate, like it did in MoP, so what will you do when the war was revealed to be a big waste of time? Or what would you do if your faction won? Or lost?
Go back to Dun Morogh, and finally sit down in the Thunderbrew distillary and have a pint with friends.
Friends who are currently waiting out bfa for the next great xpac and adventure.
Sarestha’s primarily driven by ideology - particularly centered around free will for the undead, and the restoration of Lordaeron. Presuming Sylvanas Windrunner will NOT be leading the Forsaken after the war, Sarestha’s intent would be to help her people find a permanent home, and to try her utmost to encourage a culture change in the Forsaken ranks - blind obedience to Sylvanas and the willingness to use the plague led to dire consequences. She would want to change attitudes there however possible.
The answer will be much the same if the war is a win, a loss, or a stalemate. Within whatever system she has to work under, Sarestha intends to rebrand the image of the Forsaken however possible, and do whatever she can to facilitate an ACTUAL culture change.
The only difference I can see is a small one if the Horde were to suffer a loss, which I think would be interesting to RP. Before Sylvanas’ attempted enslavement of Derek Proudmoore (and the rather suspicious circumstances surrounding the Kaldorei Dark Rangers), Sarestha was an ardent supporter of Sylvanas’ Horde, believing that Sylvanas was willing to make hard choices for the benefit of everyone. She was there when Teldrassil burned. She publically encouraged celebration back in Orgrimmar after the fact, seeing it as a genius military victory. Now that, in her perspective, she did all of that in the name of the “Lich Queen” - a slaver of free willed undead… Well. She’s actually feeling a lot of guilt, because it was the Scourge who took her life away, and the Scourge who she swore she’d break free of. In the name of a similar force, Sarestha brought that same death and suffering down on the Kaldorei, and she feels a lot of remorse for that, now that her messiah-complex for Sylvanas has worn off. With that in mind, if the Horde lost, and there were some form of war crimes trials, Sarestha would submit herself to Alliance justice without protest.
What about Enekie? 
From the bits you’ve mentioned, she seems pretty warlike. How will she take peace, win, lose, or draw?
Implying bfa will ever ‘end’ is a bold take in the age of live service models.
Anyways,
“And Lyzettie continues to stab humans in their gallbladder to this day. The end.”
Take a vacation. Find a beach void of gilgoblins, harpies, and/or any demonic entities. Relax. Maybe grow her hair out.
Kait doesn’t like fighting the Horde, especially after having fought beside them, but she’ll do what she must to preserve the Alliance-- and she knows that is what her old friends are doing, fighting for their own countries and faction.
So, yeah, she just wants a Beach Episode™.
Continue his war against the Horde until Elune releases him. If the Alliance lost, he would continue his hunt. If the Alliance won, he would continue his hunt.
The words of a human child mean nothing before the will of the Night Warrior.
Protect the Horde from all threats and ensure it’s survival, however he can until his last breath.
The same thing Vanleer does currently when not actively wrestling people into submission, he will keep writing his book about his family and his catalog the various unarmed styles he encounters.
The main difference write now is he is fighting more alliance as of late as compared to unaligned or Horde soldiers.
Keep working for his boss. Clean up work, probably focusing on killing old god stuff… really complicated question, honestly. He doesn’t trust the undead because of the things he’s heard from… well. Pretty much EVERYONE that’s not undead that he’s talked to.
If it’s an Alliance victory that sees the Horde in tact and under new leadership? He’d be… accepting.
If the Horde won with Sylv at the helm? Probably wouldn’t be seen for a long, long while.
If the Horde won with Sylv NOT at the helm? Business as usual. … Maybe start hunting LF Draenei? Maybe. He’s ignorant of how they might be different to the Lightbound in ideology.
There’s a lot of variables…
Battle is life, and expression. Dubor would eventually shelve boiling hatreds and return to work as a freelance mercenery, though be selective with whom he accepts jobs from. He would continue to traverse the world, learning about armor and weapong smithing wherever he goes, and honing his fighting technique and love of battle.
War is temporary. Battle is life. None know that better than a Blackhorn.
Not entirely sure honestly.
Wurga sort of wants to be killed during the war so that he no longer has to be a walking abomination who cant enjoy the mortal pleasures he once did… but he also doesn’t want to commit suicide.
My Pandaren will likely continue to aid the friends he has made in the horde. He does not have any hatred for the Alliance, and does think highly of his Tushui kin, the dwarves and MU Draenei. That said, he also doesn’t trust most in the Alliance to put it’s hate aside or even scale it down to the individuals who wronged them, so will still act in defense of those he calls his friend. He’d much rather not kill the instigator given the option, but if they don’t heed the ‘Go home or Else’, they’ll likely get to enjoy tea time with Bwonsamdi.
If the Horde wins, Jian will probably step back from his wartime roles. He’s seen enough bloodshed to warrant a vacation. Maybe he’ll settle down and open a noodle shop again, like he did after the events of Wrath (and just before Cataclysm: the shortest short in history).
Horde loses: Jian will probably go into hiding. He honestly has no ill will towards the Alliance, but because he was part of the Horde, he’s got a target on his back. He might even retreat to a neutral city such as MU Shattrath. Maybe open a noodle shop?
Tie/Cessation of Hostilities: Prepare for the next time.
I’m not even sure when or if any of my Horde characters will turn rebel, so the particulars of how the story plays out are going to matter quite a lot.
The experience will either redeem Laurensa of some of her worst traits or validate them and make her turn full villain. Fun!
Turuuk will probably try and rebuild what’s left of his former home, Camp Taurajo.
That would be the first constructive idea any member of the horde has suggested in regards to Camp Taurajo.
Still not sure what character development will happen with Versca as BfA slowly grinds forward. If everything ended up being okie dokie, Versca would likely be a mercenary, assisting wherever she could. If I stick with the theme of her being a screw up, she’d likely take on an unsavory job that gets a bounty put on her head.
Yet I was thinking about it, unless the brain rot gets you, Versca and most other undead are essentially immortal right? I could see her eventually getting into writing, started out as keeping journals to keep her mind active and memories of things that have passed. Yet that gradually leads to writing about her old life, the history of old Lordaeron and Alterac (where she’s originally from), then all the crazy events that have occurred afterwards into current.
If the timeline moves as slow as Blizz says it does, then our characters live in a very interesting age and this would be the kinda history folks will be reading about years from now.
Post war reparation efforts for the losing side on any of my characters on the winning side and actively on board with the war, not that I have many. History has shown IRL that when post-war efforts are not made, it gives rise to terrible things, and so having the grace to put forth an effort to make amends moving forward is a lot more productive than harboring grudges for the sake of self-glorifying revenge pathos.
If the Horde still exists as anything other than a shadow of its former self at most, Ursuola isn’t going to stop until she’s helped bring it down.
Assuming that does happen, though (yeah right), she’ll probably…I dunno, go be domestic for a while, get bored like a month in, and go back to beating up Arthas every week.
If Sylvanas wins? Grab as many friends and family as he can, steal as many ships as possible from whatever source he can, sail for an Island and try to set up a neutral community.
The Horde might be as good as dead, but the ideals remain still and can be salvaged.
If the Alliance wins, do everything he can to make sure the civilian population is spared. Orcish honor might demand you die with an axe in your hand and blood on your face, but that only applies to those who fight. There’s no honor in killing crafters and farmers and peons, and if the Alliance won’t spare anyone in retaliation for Teldrassil, then Gen is, again, stealing ships and scattering Horde civilians across the ‘Thousand Isles’ of Azeroth in the hope that at least some of them will survive long enough for tempers to cool and bloodlust to be quenched.
If Sylvanas is deposed and the Horde still wins? Hunting down Sylvanas loyalists as much as he is allowed under the new regime. We cleared out all of Garrosh’s bigoted meat-heads and murderous thugs, we can do the same with Sylvanas’s fanatical goons and heretical followers.
Then we make sure the next generation of Orcs learns more from the Tauren than they do Orcs who might be blinded by rose-tinted memories of ‘the good old days’ and lean on the Goblins to not stripmine Kalimdor in the next decade or so. We’ve gotta live here, and short-term profits means nothing if we don’t have any farmland worth a damn due to pollution and war.
Essentially, if the Horde can win (or at least hold Kalimdor effectively) without Sylvanas, he’s staying and doing everything he can to bludgeon the Horde away from being mindlessly expansionist.
If the Horde loses, or worse still, wins with Sylvanas still at the helm, it’s time to bug out, build a new Horde in some out-of-the-way corner of the world and build up their forces for the inevitable clash with the Dark Horde of the Banshee Queen.
Astrea’s entire reason for being involved in the conflict is to gain prestige among the Kaldorei in an effort to promote greater acceptance of the Highborne and arcane arts.
With the war done she’ll likely go back to whatever she was doing before; namely a project involving Naga. Perhaps she’ll advertise for an apprentice; promote her books more actively…or just go back to being a hermit.
