A small green humanoid with pointed ears and whispy hair, Yoda trainded Jedi for eight hundred years.  He lived on Degoba in a small hut, a simple existence in the perfect environment for training Jedi.  In an effort to hide from the Emporer's Jedi Purge he made his home near a dark cave where a Dark Jedi had once lived.  The dark presence there cancelled out his incredibly strong Force and hid him.
  He usually only had one student at a time, including Obi-wan Kenobi and Luke Skywalker.   He had a rather odd speech pattern and was very patient, always pushing his students one step at a time.  After Luke left to save his friends, Yoda became very sick and died upon his prodegy's return.
