Ageless because he can change it by twisting time. Immortality is another thing entirely. He still ages, and he's still killable.

In short, imortality is a no no. But being Ageless is acceptable, because it doesn't mean he won't die eventually. There was comment Where I put the entire matter to rest a while back, but We deleted it because I had to reveal a major plot twist in order to sort it. So that has been resolved.
