So in oblivion, you hear that the morrowind player went to akavir and hasn't come back. In Skyrim a certain Daedra makes reference to the fate of your oblivion character. In VI we might hear of what became of the dragonborn/TheChosenOneForEverythingDueToBadWriting.
But, I want to see what the community thinks those characters are doing/what are their traits. Because all of them were pretty limited due to gameplay reasons. What are they like in lore?
My thoughts on the matter:
The nerevarine mastered all the skills. All of them. So although a master of the blade (able to hit a mudcrab over 99.9% of the time) he also knows the widest array of spells due to mastering every school. But most importantly, he understands Chim. This, combined with the fact that everyone recognises him to an annoying degree, caused him to master the art of changing his race whenever he feels like it. The public thinking he's 'away in akavir', he really just wanders the world compulsively looting everything. When he does fight, He flies out of reach, becomes entirely undetectable and invulnerable. His armour is very indoril- like, and he wears wraithguards on BOTH hands, because CHIM
Champion of Cyrodil
Stuck in the madhouse, thinking he's some kind of Savior to sheogorath, when really he just went mad.
Dragonborn
Wears Dragon bones. Uses melee and shouts, because normal magic is very poor in skyrim. Got lost in a library, searching for a good writer, but never finding one.
(okay, that one was a bit [censored]y. but what do you think happened to the heroes after they stopped being played?)
