Ah, crap, I forgot to fill in the "powers" section for Cu. It's derived from the riastrad, or warp spasm, also known as frenzy, that Celtic warriors get during battle. However, for Cu, I'm making this different from his heightened stamina during battle. If he gets wounded too deeply, or sees too much blood, he might transform into a giant wolf-like creature who can't differentiate between friend and foe.
