Ok, so there is an excavation just a tiny bit south-west of Winterhold (forgot name of excavation). I was sent as a second lesson in the college with 4 other students. I have been asked to retrieve 4 magical artifacts and have only found 1, an amulet (not sure if I have missed any).
I have come across a combination lock of 4 pillars each consisting of 3 sides, a fish, a bird (or hawk maybe) and a snake.
If anyone knows the combination (or if I have missed any artifacts) please tell me in the form of a spoiler.
