Talk about your current fortress - trials, tribulations, successes, and failures. This would also be a great place to post your long fiction of your fortress.
Most recently, my fort, Cobaltshowers, fell to a mistake when placing a giantess in my blood-sport arena. This mistake saw the giant, and swarms of goblins, released while the bridge to my fort was still open.
My militia could not organize in time, and the swarms overtook me. Good times!
I too start far more fortresses than I finish!
