I finally retired my fortress Torchsyrup, after achieving a fair portion of my goals there. My empire, the Reclusive Lashes, was at war with another Dwarven empire, the Crystal of Barricades, and came pretty close to wiping them out.
My new fortress, Tinspun, belongs to the Crystal of Barricades. My main agenda for this fortress is to build lots of cage traps, capture all the legendary warriors from Torchsyrup (which is very close), and steal their adamantine armor.
Tinspun has been thriving for nearly 20 years, but it has not been a complete success. While I have managed to capture scores of enemy dwarven soldiers and steal their armor, none of them have brought any adamantine. And the only recognizable dwarves from my old fort have been a pair of necromancers that showed up and were swiftly captured.
Due to my over-reliance on cage traps, I haven't had much of a military for most of this playthrough. But i have vast stockpiles of stolen steel armor, and about 20 smelters constantly melting whatever isn't worth saving.
The King and his Queen Consort live in Tinspun, along with their 11 children. The eldest are teenagers, currently training under the militia commander. Once they build up some skills, they will be given their own squads, and I'll start building up the army. I've also let them spend some time as scholars, and a couple of them have written autobiographies.

One thing I've noticed - I'm not able to invade my previous fortress, Torchsyrup, apparently because both fortresses occupy the same tile on the world map (unless there's a way around this, which I'd be super grateful to hear about!). I wonder if this is also preventing a direct invasion from Torchsyrup, keeping me from getting my old citizens as invaders?
