you're nothing but a simple beast that's played in the mud
[Personality ref & color ref] - she also describes herself as privimitve and calls herself the savage, in other words a simple beast. She is brown, as is mud.

There's blood on your hands that you don't even bother washing off
[History ref] - she killed Irc and also some horses in her previous life outside Helovia, but certainly feels no remorse.
Your legend has just begun, master of the elements
