In my dwarven universe, violence is some kind of horrible voodoo curse that destroys everyone it touches. I started off okay. A miner was surprised by three lizardmen jumping out and screaming "boo!". He then proceeded to crush their skulls into a fine paste without so much as a scratch on him.
Later, a trapper's arm was wounded in killing an alligator. He went to bed, and got fed and watered. He slowly began to go insane, and started to tantrum constantly. Eventually he healed up.
He'd be okay for a while, and then suddenly tantrum, stopping his hunting to come back and whine. At one point, he got so pissed that he beat the metalsmith's pet cow to death in the dining hall. A few days after that, he flipped out and killed a dog, and then killed a nearby dwarf. Two other dwarves found themselves honorary members of the "CUT THAT THE HELL OUT" brigade and were sent to deal with him.
They died.
Then the same miner who killed the lizardmen waltzed by and beat the crossbow-wielding jerk to death, again without being scratched.
So, basically, I have a tomb now.
Oh, and before I stopped the game for the night, a dwarf fought off 4 lizardmen. Was wounded.
She is now tantruming, so she was locked in her room to die a slow and painful death, because I know how that story ends. With blood.
