i was exploring when i found unmarked cave "the chill" inside was 3 cages with skeletons on bedrolls in them. and there was a frendly frost atronach there. then he turned unfriendly. i walked outside and got attacked by 3 other frostys. easter egg?
i found this too not long ago....pretty cool, I'm betting it's out of another movie or game or something and they just added it in for sheepsandchickens(<-trolol)
