So there was this bronze colossus giving me crap (actually, he was pretty cool, killing off a whole bunch of zombie elephants and mandrills for me, until he followed somebody into my fortress--I thought I was done until a brave, brave stray cat he was chasing (after smiting a few dwarves, mind you) led him out of the fortress and he went back to his spot) and then my third goblin siege spawns in on top of him and after a pretty impressive battle they finish him off. The goblins rallied and advanced on my fortress--we're talking about 30 goblins and 15 trolls left, though the colossus seemed to kill only one or two (he did get swamped by them, to be fair). My last dwarf outside was running in, and he almost made it, until this Goblin Mace Lord--the King, it turns out--runs up and bashes him about 4 tiles away from the fortress entrance. A hush falls over the battlefield, as the assault is prepared, and then they charge, led by the King. As it turns out, the first trap I have is a cage trap, and the King gets caged. This took a bit of steam out of their attack, and even though they still breached the first line of defense they were turned back at the second. As they retreat, my captain of the guard charges into them and turns it into a rout--she was smashing the greenskins left and right, laying a bloody trail of body parts; quite amusing to watch, in fact. At the edge of the map, a goblin spearman gets a lucky strike in on the captain, and even though he is promptly dispatched, a zombie elephant kills off my poor captain, sustaining mortal wounds in the process. She will always be remembered as a heroine, etc. etc.
The question is: what do I do with the goblin King? Currently I have him in a cage in the zoo (he's the main attraction now!), but I was thinking about moving him into the room I dug out to put the colossus corpse--er, masterpiece bronze statue--in. I thought it would be rather ironic to have the King staring at the colossus that he worked so hard to destroy. (Were I to do this, should I define the room from the cage--a zoo--or the statue--a statue garden? Would it matter? What if I made two overlapping rooms?)
Alternately, should I let him out and kill him? (Let him out in a heavily trapped corridor, of course.) Or chasm the sucker? Drown? Magma?
Would any of this have any effect on the greater world? Would they get a new king? Will they stop besieging me if I hold their king hostage, or try to rescue him? Or will they stop if I kill him? Or neither?
(Also, one of my jewelers went nuts and made a perfect gem. He then went outside and got ambushed and eaten by a cave croc (how the croc got outside, I don't know). Nobody will haul the damn gem back in--I have empty stockpiles--and some damn zombie mandrills keep picking it up but are too slow to make it away even before my pathetic military gets there to kill them. How the hell can I get the gem back inside? And what should I do with it? It would be sweet if I could encrust the colossus corpse with it... hehe...)
Thanks for any suggestions!
