You return Jerdek's Shard to the Snowmask clan. They are quite grateful for what you have done. They no longer consider you outsiders, but instead consider you Snowmask Brothers and Snowmask Sisters.
As part of the ritual to induct you into the clan, you are dunked into ice cold water, blessed by the tribe elders. For a moment, your skin turns white and you are freezing. Then your skin returns to normal and it's not cold anymore. In fact, you feel fine. The Snowmask tribe shouts in celebration; Their new honorary villagers are truly home!
...you did remember to give Skagni that chest, right?
