Known as the "Old Man" of the party, he personifies the very aspect of shadiness. Raven constantly complains and treats everything he has to do as a pain in the ass. Whether the stories he tells are full of lies and deceit, or the constant changes he makes to his answers, he can be a very troublesome man indeed.
That being said, he is not a bad person. He acts as a father figure to the group and can say some surprisingly wise things.
