Actually, like all three realms, the only quest needed is the common ground quest.
Right at the entrance, level 35 quest; kill 3 missionaries, return and you have neutral faction... then with a stone you can talk to the lady near the entrance to the town wearing all DS armor to get as many pieces as you have stones.
If you are talking bare minimum without running those quests, it gets a bit more complicated.
Have to get faction (the Road to Svarhamr, A Letter Home), Battles in the Mist (pretty tough), Yar (Pretty tough); then a round of 4 baby dragons per armor piece... the stones are sooooo less complicated rofl!
