Sorting my way through a huge migrant wave, 30 some people. When : Ilral Tizotuzol Shetbeth an has come! A large hedgehog twisted into humanoid form. It is crazed for blood and flesh. it's eyes glow yellow. It's charcoal hair is long and wavy. Now you will know why you fear the night..
My reaction? "Oh crap Oh crap Oh crap Oh crap Oh crap.... bunker down bunker down, hurry migrants hurry.... what the?" Because i suddenly see the werehedgehog attack a swarm of cavy's RIGHT OUTSIDE MY FORTRESS WHILE SWARMS OF MIGRANTS RUN BY! Taking advantage of this i mobilise my military, i.e recently drafted migrants to attack. The werehedgehog tears one of them's stomach and chest open with a bit, claws two more people before turning back into a dwarf and being sniped by one of my archers. Needless to say the bitten dwarf is now burrowed on the other side of the map, suffering from infection while i wait for him to turn so i can kill him.
Other than that i'm hastily digging out a barracks and more rooms for the 30 plus dwarves, half of them children, who just showed up at my fortress. Luckily my inner walls are complete and the outer walls are being designated.
Edit: And now i've lost a recruit because the werehedgehog former civilian attacked him, he fought back, the werehedgehog changed back, then my archers shot and killed the recruit.... Dumbass dwarves.
