So Utheg Bomrekaztong, a huge hairy pterosaur has come! It has an enormous shell and it undulates rhythmically. Its tan hair is long and shaggy. Beware its webs!
This worried me slightly, as my fortress is in a human fort (walls and everything), embarked using embark anywhere. So it could just fly over the walls. I sent my two military dwarves to fight it: an axedwarf and a marksdwarf. The axedwarf Thikut Umstiziton Onolonul Tilesh ran in, and promptly got entangled in the webs and his upper spine nervous tissue damaged. This was on Malachite 22nd.
The marksdwarf Zasit Sarveshtorish shot it a little bit, but it didn't want to stop webbing its prey. All that week, even after Zasit ran out of bolts and beat it with his hammer until he was proficient, Utheg shot out thick strands of webbing. Eventually, Zasit went and took a nap, got a few more bolts, and came back. During this time (1st Galena) Utheg opened an artery in Thikut's head.
Utheg had taken to the air for a bit (no idea why). But Zasit broke both of his wings, so he got stuck in the air for a while. Oddly, so did some of his webs. After a while, Zasit decided to go to archery practice, and Utheg was busy spewing out webs 1 z level in the air. He wouldn't stop until I deconstructed the archery target.
Eventually Zasit wandered too close, and Utheg got his in his webs. So I decided to build a platform on which I could build a catapult and shoot Utheg out of the air. Meanwhile, it's 16th Galena and Thikut still hasn't called it quits despite his health screen saying "heavy bleeding" and "cannot breathe" and his thoughts screen saying "His head is torn open. His head is gouting Thikut Sizzlehall the Mountainous Mirror of Trusses's dwarf blood. His head is bruised. His upper spine is broken."
Then, on 16th Galena, a human caravan showed up. And the undead, including 3 necromancers. And some goblins. The undead finished off Thikut and Zasit, so we'll probably never know what was happening there.
Do forgotten beasts heal, or can I just leave him up there forever?
