His coat is mostly ashen, with darker points of charcoal at his extremities. In the shadow of his face, his blue eyes are especially striking. Cathal is hilariously expressive, which is another way of saying he's a terrible liar. Even if he wanted to deceive someone, his face would give him away. Or his ears. Or his tail.
Perhaps it's for the best. He isn't smart enough to come up with a decent lie, anyway.
Family is everything to Cathal. Much of his time is spent caring for his younger siblings or playing with one of his cousins. As a pup, he deeply admired his father, who died in battle before his children were even a year old. Cathal knows the consequences of war, and still, he romanticizes such heroism. The question is, will Cathal live to be a hero? Or will he die as one?
