When my kobold architect/expedition leader has went berserk due to a single sturgeon killing off all of his friends. He waits in the lower cavern, carved out for the meeting hall after cornering two others and beating them to death. He leers from the behind the sandy staircase, ready to pounce on anyone decides to go down there for idling. Another is taken by surprise, becoming victim to his violent and bloody building-design-skills. Another. He begins to wait at the bottom of the staircase in seething rage, just waiting for a glimpse of another.
A weaver decides to go take a nap, walking down the hallway to the staircase, and suddenly a kobold who he once knew as a friend lept at him, fiercely beating him with a fresh kobold arm with.
He leaves the corpse and waits for others to massacre. I notice I am starting to enjoy this.
A stoneworker and a clothier trot down the hallway together, disregarding the corpse, and of course, get attacked by the crazed kobold. They both run out into the forest outside being chased, calmly conversing over who should take over as expedition leader. The stoneworker takes the duty and a turn to the left, ditching the clothier. Eventually, a human caravan comes by, and watche as the kobold is chased in circles around the forest. The architect finally catches up to the clothier, and beats him senseless by the river, as the humans linger nearby behind the trees, watching. The killer collapses due to over-exhaustion, and the victim to pain. Eventually I just decide to send the stoneworker to kill the lunatic and perhaps save the severely mangled heap of flesh. He does, although, alas, the victim dies due to blood loss right after, in front of the stoneworker: the last kobold standing. He then abandons the camp.
I know it wasn't the bloodiest massacre in DF by far, but I thought it was hilarious, it being my first experience with Kobold Camp.
