The company Illwinter was orginally called Bogus Games.
Bogus and Company is an in-game representation of the Illwinter developers group of DnD adventurers they used to play with. They have some things (such as orders) which used to be in the game but got removed later.
And yes, they kick ***. One suggested tactic is to not fight them together. Use assassins, or better yet seducers.
