Hey, I remember climbing that.
Apparently Solstheim island is part of Morrowind, which is cool in that you can see the ever active Red Mountain in the distance. The small town of Raven Rock is where BT and I make land fall, meet the locals (mostly dunmer as expected), and get a bunch of quests like hunting netch (flying jellyfish), clearing out ash zombies from the temple, and investigating a strange stone that seems to make people mindless zombies who want to build - something. Even BT began getting entranced by it.
BT: "It's just sooo big..."An adventure into the local mine to find the remains of some guy's missing relative also leads to familiar looking ruins and even more familiar looking draugr. There's even a cool lazer sword inside, too bad it's kinda weak. While the enemies are no problem, the last pendulum blade hall proves too much for B.T. and she is cut to pieces half way.
At the end of it I find not only a new dragon shout, but an odd black book which warps me into the black/green/tentacled realm of Apocrypha. With walls made of books and scrolls it's easy to see why its ruler, Hermaeus Mora, is regarded as the prince of knowledge. There are some abominations lurking in there, but none really pose a challenge. Having a choice from three boons at the end of the level is a pretty good idea too.
Walls of books go well with Cthulhu.
