Timothy Paradox

I recall accidentally falling all the way down from an incredibly steep icy mountain (possibly with a fortress on top), all the down down to a lake.

Down in a lake with a bunch of other people. Possibly living in the water? There was another lake right next to it, but it wasn't connected to ours, so we couldn't reach it (we couldn't move on land?). A group of other people was stranded in that other lake, but I didn't care, as the water in our lake was warm an their was cold.

I vaguely recall a sex scene, or rather: an attempt at sex. It didn't go very easily.
