TEXT: 
  Tremor is a 25-foot-tall bear that dominates the Wallingmiotta.
  While many believe Tremor is one of the Great Titans, this is
  untrue. Tremor was created spontaneously through fey magic.
  He now acts as the ultimate protector of the forest. Tremor
  does not move through the Wallingmiotta quietly. He can be
  spotted or heard from 300 feet away as he crashes through
  the trees and underbrush. Any creatures he sees as hostile
  towards the forest he attacks and fights until killed.
  When he is not hunting or protecting the forest, Tremor
  retires to a 100-foot-tall cliff face located south of the
  Neepawa Bowels. At any given time, there is a 10% chance
  that Tremor is resting on the cliff.
  However, Tremor is not alone. A harpy named Yoraene lives
  on the cliff with Tremor in a nest made from discarded plate
  mail armor. She uses her song to soothe and calm the bear so
  he can sleep. More clever than most of her kind, Yoraene
  enjoys testing creatures who dare approach the cliffs. Those
  who pass her test will be given safe passage through the
  forest. And those who fail her test are instead eaten by
  Tremor. So far, no one has passed her test. She worries
  Tremor is getting fat.
