Pedantic Grognard
I was incredulous when I read the novel in 1993.Yep. He stabbed him so hard he ascended.
I mean, okay, turns out Kelemvor's soul has been hidden by the intelligent sword that Cyric stabbed him with for the last decade, fine.
The sword was, it turns out, secretly Mask's avatar, okay.
Cyric breaks the sword, and Kelemvor's soul gets out. Not a problem.
Suddenly, without doing anything, Kelemvor has ascended to godhood -- wait, what the hell?
