 In town of Glacern, the mule seller is running a business called the  Frozen Yak. This was based on a prank perpetrated by Cavedog  Entertainment on April Fools Day in 1998. Just for the day, Cavedog  revamped their website and announced they were changing their name  to Frozen Yak Entertainment. Prior to the foundation of Gas Powered  Games, Chris Taylor, Neal Hallford, Jeremy Soule, and several other  Dungeon Siege staff worked for Cavedog Entertainment.
