My WTF moment was when Alberic Litte, of the Chorrol Mages Guild, sat down to dine with his peers in the upstairs dining room. He clipped through some piece of dinnerware on his attempt to sit, and the item began to resonate. It kept shaking more and more violently, and was finally launched-- like a rocket plate-- at the maximum speed the engine can handle, into the rest of the table set and food. Items simply exploded out and bounced all over the room flying. The noise of objects hitting things was really loud and intense, because there were dozens of collisions all at once, and the chaos lasted several seconds.
None of the mages seemed to notice that anything unusual had occured. Alberic Litte remarked vaguely that he heard daedra worship was becoming increasingly popular in the Summerset Isles.
Entering Rockmilk cave and hearing a weird rattling noise. I headed towards it and found a massive spiky thing on a chain spasming and whirling around the room for a few seconds, swatting bandits, marauders and even Mazoga before reattaching itself to the ceiling :shrug: WTF was my only response to it.
Nice. That's REALLY strange. Another WTF moment (that everyone experiences) in Rockmilk cave is the bosmer that falls from the cave ceiling at the beginning. It seems like wherever there's insanity in TES, there's probably a bosmer.
