Joining the Stormcloaks

 There are several ways to join the Stormcloaks. The first is by random chance. When you enter Helgen's Keep, you have about a fifty-fifty chance of entering with either Ralof or Havard. If you enter with Ralof you will attomatically get the quest when you leave the keep. If you enter with Hammond, then you can either go to Windhelm and talk to Ulfric Stormcloak or talk to farmers and stormcloak soldiers. After you get the quest then travel to Windhelm and find a building called the Palace of Kings. Speak to Ulfric and he will tell you to talk to Gamar. Gamar will then tell you to prove that you are a good fighter by travelling to the serpent stone and killing an ice wraith. leave the palace and travel north. The serpent stone is located on a floating iceberg in the middle of the sea near the end of the map (north of Windhelm, east of Winterhold). Kill the ice wraith. travel back to Gamar and he will tell you to recite the oath. recite the oath and contulations you are now a stormcloak.
