A group of adventurers come across a child’s body on their adventures, odd being such a remote location. Their is no detectable sign of violence to the child, nor are their any signs of life. Suddenly the child opens its eyes, looks towards the group and introduces themselves to the adventures.

The village sits on the edge of the deep fjord, often engulfed in mist or rain. Its people are fishermen, who work even through the sea-ravaging winter. And they pray to the gods of the deep.
At the beginning of every winter they hold a summoning ceremony. Three boats are taken out into the fjord, a hornsman on each. The mournful horns are blown in the language of the whales, the gods of the deep. The whales sometimes appear in answer to these calls, and it is taken as a good omen when they do.
