My monarch moved their court to my fortress some time ago, and shortly after they arrived I got a message about Barons and Baronesses visiting. Which ended up being about 33 visitors. Around 7 were goblins, the rest were dwarfs. The queen is herself a dwarf as is her consort. They've been hanging out in the temple for about a year.
The fortress came under siege so I activated burrows and brought everyone inside. 3 goblin snatchers arrived at the same time and moved in immediately, and the moment they got close enough for my marksdwarfs to start shooting at them, most of the visiting nobility went hostile and massive brawl breaks out in the temple. Unfortunately for them some wardogs and some tame grizzly bears were also in the temple, and started tearing into the goblins. Then everything goes crazy.
The stray grizzly bear bites the goblin in the head
the stray grizzly bear jumps out of the stray grizzly bear's flight path! (wtf?
)
the stray grizzly bear slams into an obstacle! (artery opened by impact)
The bear attacks the goblin again and proceeds to shake the goblin around by the head until it dies.
Another bear charges a different goblin, but the goblin deftly keeps dodging, the bear plows through the crowd, and knocks a cat aside somehow without injuring it, charges again and slams the goblin. Then it bites into the goblin's stomach and chews them to pieces.
The wardogs get some, and also proceed to throttle some of the gobbos to death.
At this point, a military squad on the way to station and await the invaders walk by the temple and decide to join in. Then the combat log turns into a chaotic mess as the Red Wedding from Game of Thrones seems to be re enacted inside the temple. The soldiers charge in and heads and limbs start flying everywhere. Blood pools and spatters covers more of the temple floor than not. Moments later, 17 of the 33 or so visitors lay dead. Barons, Baronesses, consorts, and I guess their entourages of peasants and such. As far as I can tell, none of my people were injured or killed. A few of them are still praying while the room is covered in limbs and viscera.
It started the moment the goblin snatchers were attacked by the military. But they were snatchers - can the nobility of enemies visit your fortress? Why would they come with my monarch? Of the 17 dead, about 5 were goblins and were the first to die, but the rest were dwarfs. Dwarfs raised by goblin snatchers, perhaps? None of my zones allow outside visitors, so other than 3 monster slayers (which didn't participate) there have been no other sources of visitors. There is one lone goblin baroness who has been left untouched. The temple was deep inside the fortress, where the snatchers were on the surface level when they were pelted by crossbow bolts.
I was unable to find what caused a grizzly bear to be propelled into a wall. Can creatures slam themselves into walls on a missed charge?
The goblins in the actual siege made it to the front gate and then just noped out and headed off without any conflict.
I'm very confused.
