We were in Runvid's Cairn, about to disrupt some runes on gholem-type statue things. We succeeded, and they didn't come to life when we passed a certain point on the map. Instead, we found a room with a tomb, and a shield on the wall. A shield that, as it turned out, gives out bolts of lightning when you touch one of the rocks on the burial mound thing.
After various unsuccessful attempts at disabling the lightning trap (we later found out you're not supposed to be able to) we gave up, and left. Turns out the forge thing was best left alone as well, so Murmei was right to insist not to become a blacksmith. Of course later he took the skill anyway, because it meant he'd be able to patch up Knightlight himself.
We continued our journey and came across the Fortress of Solitude. Despite his previously flawless negotiation tactics ("hi, let's be friends!") Murmei was unsuccessful with the ice trolls, who decided the party would be best eaten. The party disagreed, almost wiped, but finally took out the lot of them, and got a fancy magic spear in the process.
Turned out there was a ginormous wolf creature, who had apparently eaten a dragon previously, guarding a big door inside the ice cave. Elindra talked to it, but it wasn't being helpful either. Apparently there's a portal to another realm behind the door, and the ice trolls want to take over this world, but so far they haven't come very far ... and besides, they're also trapped inside a big bubble you can't simply walk out of.
At any rate, we got out of there, found a treehouse, rested up, and we left off having found a couple of dead ice trolls and a dead boar, and the air was getting chilly again ... to anyone not wearing a cold immunity ring.
