If you had to put the Heroes of the Elder Scrolls' prophecies into a definitive character how would you do it.

I would do it as following

Arena: A moral Argonian knight
Daggerfall: An anti-hero of any race. Both a vampire and an agent type character
Morrowind: Imperial battlemage
Oblivion: Redguard/Darkelf (Don't know why, just thought it would be cool) Witchhunter-type of character.
SKyrim: Nord battlemage
