Thanks, Luna! I also agree with what you said.
After all, wouldn't it be true that the first time Rayek ever saw an elf dominating/controlling another elf would have been when he met Winnowill? It certainly isn't something Savah would have taught him about, and Rayek's own sense of superiority manifested itself in being a loner, not a controller.
Controlling, enslaving-- that's something trolls did, something he couldn't forgive them for doing to Ekuar. It was Winnowill who introduced the concept of overpowering another for his/her own good. Before that, it wouldn't have been something that necessarily even occurred to him.
What a team we make, right Lunakat? :D
