*shrug* I'd never heard of Morgana until after I designed Viyana (I don't play League). It seems like she is pretty much your basic demony lady, so any character that is female and demon-like is gonna have some resemblance, I imagine.
So as it turns out, Viyana has been my best toon so far. I'm not a huge MOBA fan, but thanks to you and Nicholas, I signed up for the beta and I am not disappointed. I told Nicholas, and I'll tell you too, I like it a lot better than DOTA 2 so far. The art designs in particular!
