Mmm, that always seemed to be the big thing about Sanguis, the mood swings and aggressive stuff...the animals I've seen out of it are kind of cool, but I wouldn't have liked that part.

[Ren very much likes being able to have his emotions completely under control. Cordis essentially just accentuates aspects he already has, so it's a lot easier to fine-tune his behaviour to suit.]

I guess you get cold-blooded...none of the Cordis animals are like that, so I guess we get it a bit easier. Though I've heard feathers are really difficult to handle.

[He's only gotten feathers once, so he can't speak on it as much as some people.]
