After noticing that one of the wild ravens on my map has a name, I was compelled to investigate recent combat reports, because being named suggests having kileld something, and being a raven suggests an inability to pose a threat to... Well, anything.
What the reports revealed was... Disturbing...
I had already known my outpost liaison was a shaman, and that shamans have the power to transform into a raven. So, apparently this flock of ravens chose to harass him, leading him to "flee" from the wild beasts, which is the cue for the transformation interaction to take effect. However, the liaison didn't flee rapidly, as that interaction is supposed to permit; a way to rapidly escape enemies and shake off wounds they'd inflicted. The Liaison instead engaged them in a mid-air battle, no less than 27 z-levels above the ground. During this fight, he apparently transformed back into a dwarf, and fell the full heigth back into my animal pastures, and exploded on impact.
So, now there are dorf bits and blood scattered all over my animal pastures, and a smug-ass raven flying off with a new title; "Sneersstruck," because she was the last thing to attack the liaison before he plumbeted to his death.
I just know that raven is going to become a quest target for later adventurers.
