The entire adventure consisted of three images: me standing on ice, it showing me flying and submerged under water after I'd moved 1 square, and the entire screen filled with white ice walls.
Y'know that situation sums up a lot of DF in one go.
Someone should draw it.
Or screenshot.
Anyway, I tried in vain to reclaim my old fort with an adventurer. 16 different ones in a row, every single one of them dead by various hilarious means, mostly the guy who drowned in a pond after single handedly slaughtering an entire goblin camp, because I forgot to give him Adequate Swimmer. Then the next one did have it... and was promptly encased in ice as soon as dusk fell and the pond froze completely solid. Apparently the nights here are REALLY cold...
The best attempt I got was a Steel Dwarf with a good sword and armor who actually managed to reach the site after starting out with the orcs close to the site. He did in fact get into it, looking for the full set of Adamantine Armor that the fortress left behind complete with short sword and maces... when the cat demon master that had killed the fort came and scratched him in the head. Literally. And it sailed off in an arc. Oh woe.
At least it was kind of a fun adventure, if frustrating...
(And I now know why I was getting so many sieges - apparently I set up the fort in the middle of Snakeman territory, right next to two other Snakemen tribes, two demon civs, three illithids and a couple of werewolves. Plus gobbos and kobolds. The centaurs didn't survive worldgen, along with the nords, or I'd probably have gotten them too. It does explain a lot, in fact...
