“...Have you encountered others like me, in the mines? I'm sorry if they were hostile towards you. You see, we've learned to fear humans... there have been too many... unpleasant encounters.”
— Krobus
Krobus is the only friendly monster players will encounter. He's a shadow brute who lives in the sewers. He lives there because he's too sensitive to sunlight to go outside during the day.
Krobus is a shadow brute and, although he isn't hostile, still refers to other monsters as "his friends". He lives in the sewers and isn't seen outside interacting with other villagers. He dislikes dwarves, stating that a 1,000 year war between the dwarves and his people recently ended. He believes if the dwarves knew where he was, they'd send an assassin.
The Wizard is aware of his presence and intervenes to prevent conflicts.
