"Maybe...maybe I'm looking at it wrong. The immortality isn't strictly the least believable part of the story, but how it was lost. As if mortality is a disease one can catch. But if Hawke really killed Corypheus and he's alive again, it wouldn't have anything to do with elven magic. He's a Tevinter darkspawn magister. If anyone in Tevinter had once learned some elven magic that made them unkillable, we would definitely know it. And still be under Tevinter rule."
