My totally useless fine noble also had an unfortunate accident..
Said noble was a baroness, who, not content with constantly changing prices of goods, decided that she wanted to ban the export of clothes (which where the main thing i bought caravans crap useful goods with.
This was bad enough, but then she decided she wanted some petty crafts made with a metal i don't have, nor will get. I was consigned to my fate when said noble had a fortunate horrible accident.
It was like any other day, and the baroness, was walking past the catapult/ ballista range, when she saw something that entranced her.. There, in the middle of a range stood a fine rock lever, that she just felt compelled to pull and pull!
Then, imagine my glee shock when half the fortress suddenly felt compelled to run to the range and fire every single siege weapon, while the baroness was still pulling that lever!
Fate was cruel to the baroness that day, and tragically she died after sustaining a ballista wound to her whole body! even better] worse, one of the baronesses many children had wandered onto the range in search of it's recently bisected mother, and was killed as well!
It is of no relevance that the operators who fired the fatal shot(s) somehow inherited the baronesses lush living quarters..
