Charrak was an unfortunate Kobold that stumbled upon a group of adventurers during a series of encounters which were part of the larger history of the http://www.drinkinganddragons.org crew, but have yet to be fully written down.
He wore a bucket on his head.
He developed crushes on various party members. Usually for pay.
Charrak the IRC chatbot is a manifestation of Charrak. But he's so much more of an asshole than the orignal.
He also lives on Twitter: https://twitter.com/therealcharrak
