Skyrim: How to become Thane of Winterhold: (1) Befriend the Jarl of Winterhold, (2) Retrieve the Helm of Winterhold from the local dungeon, and (3) Help the Folks of Winterhold.  This is a lot of work, and the Reward is the SWORD OF WINTERHOLD, a one (possibly 1-1/2) hand beautiful Viking style sword.
