My captured and trained Gremlin petitioned for citizenship, and has been appointed as a militia captain. Dwarves aren't able to produce any armor small enough to fit gremlins via the details menu, but using Dwarf Therapist to enable Armorsmithing and Leatherworking and Workshop Profiling has allowed her to make her own equipment, sized to fit. Also, gremlins are too small to wield any weapons except for daggers and spears, and have rather severe issues with encumbrance, so she's been issued an Adamantine spear and Feather Wood shield. She's now working hard to improve her Armorsmithing until she can produce a full suit of exceptional/masterwork armor, at which point I'm going to see if I can get a titled Gremlin Spearmaster. I wish I had the artistic skills to properly portray a fully armored gremlin, all of maybe 10 kilograms, armed with a ridiculously oversized spear and a shield that's probably as big as she is strapped to her back, taking on foes hundreds of times her size.
Meanwhile, our Hydra breeding program continues to bear fruit, with the latest generation bringing us up to 25. The Giant Cave Spider program has also produced enough surplus spiders to provide all entrances to our fortress with webbing turrets. First test on a handy invasion of trapavoid Nakashim proved the effectiveness of the design, though three hapless military dwarves also were caged when I attempted to deploy them through the same gate on cleanup duty. Also, a webbing, flying Forgotten Beast attacked, but for some strange reason decided to park itself in the single-tile space at the bottom of my 30+ Z-level drop shaft, trapping itself quite nicely. There was already a 3x3 ring of 3-Z high walls with a single door at the bottom in order to make retrieval of exploded body parts easier, so I just walled off the door and the roof for now as insurance. The question is, what do I do with it? Maybe I should turn it into a silk farm or something...
Finally, last summer the Elven diplomat, after finishing his meeting and retiring to the tavern, took it upon himself to attack the visiting Human Guild Representative, and was rapidly dismembered. This summer, the same Guild Representative decided it would be a good idea to punch an armored war elephant mercenary, and got his skull crushed for his trouble. Strangely enough, this passed his position to one of my resident bards who'd already been accepted as a citizen. I have no clue what this will do to future diplomacy.
