You are a primal elf, dwelling in Arvandor together with all the cool elf gods and your dad-mom-parent-familial-unit, Corellon. Lolth, who goes against him, has gained some of supporters, but you remain on Corellon's side, as do most primal elves. Lolth tries to kill Corellon so you rally to his defence, and she is defeated.
Corellon nevertheless decides to cast everyone but the elf gods from Arvandor.
You wake up, in a completely permanent physical form, in the Feywild. You mourn your loss of Arvandor for decades. Finally you move on to the Material Plane. After like two centuries, you start getting over it all, surely you can make life work here, even with the constant guilt and loss you feel.
Eventually, as is the fate of all mortals, your natural life draws to a close, you die as a respected clan member, surrounded by friends and family. Finally, respite.
You wake up in Arvandor as a soul, not a physical being. "Yes! Finally! I'm back!!!" You think to yourself. Except then the Seladrine show up and tell you "btw you're only here temporarily, you will return to the Material Plane eventually." Okay, so that sucks, but at least you get to enjoy Arvandor, right? Well, after a while the Seladrine leave you alone, and all you can feel is that Corellon isn't mad at you, not really, he's just DISSAPOINTED. He also lets you know, wink wink nudge nudge, he would be much less dissapointed if Lolth was dead and if the drow get genocided along the way, oopsie daisy I'm so whimsical and fleeting.
You awaken back on the material plane in a different body but with hereditary daddy issues, trapped into an eternal cycle of torture.
Your hereditary daddy issues and homesickness eventually get so strong you can't take it anymore. All the strongest elf mages of Faerun try to pull a part of Arvandor into the Material Plane so at least they have some place to call home.
The ritual succeeds, but the part of Arvandor (now called Evermeet) eventually detaches itself from the Material Plane, becomes unmoored somewhere in the Astral Sea, and everything you've done has such a catastrophic impact on the world the event later gets called "The First Sundering" because you cracked continents, shifted rivers, fucked up the very space-time continuum itself, and caused deaths on a scale that will not be matched until way later, when someone literally destroys magic itself.
