Nordsjoen was a small covenant on the Shetland Islands. It consists of a number of small circular stone buildings set atop a rocky cliff top, access to which is limited to a narrow rocky path up a steep cliff.

It was severely damaged by a supernatural storm in the summer of 1225, and the maga Abigail ex Miscellanea was killed when part of the covenant collapsed on top of her.

The other two magi, Einar ex Miscellanea and Masque ex Tremere moved to Loch Hourn.
