Around the end of year 1, a flock of giant cockatiels got husked at the same time a migrant wave arrived. This particular wave contained a dwarf with extremely high metal/weaponsmithing, so I needed to save the migrants if at all possible. My pair of axelords was down in the first cavern layer, having just dealth with a rutherer, but fortunately Bim Yearlinggloves, one of my hunters, was around to distract the cockatiel husks long enough for them to be puréed via ☼steel battle axe☼. The master smith entered the fort unharmed due to the efforts of Bim, who, though he survived, lost his left hand in the process. I gave him the custom title "Valiant Defender" and planned to assign him special lodgings later.
Later on, a human necromancer entered my map and began reanimating a few corpses. I quickly sealed the fort and set cage traps in an attempt to catch him, but another migrant wave arrived, forcing me to briefly open the entrance again, and what should wander in after them but Bim's now-skeletal zombie left hand? It ran straight into a cage trap.
I'm constructing Bim's room currently. The centerpiece? His own hand in a lead cage.
EDIT: Ooh, just as I type this, a bone carver finished an artifact — a forgotten beast bone sword called "The Incidental Breaker." I shall have to find a ceremonial use for this.
