Yorick Silverwing is a pilgrim in the underworld. He traveled with two other bats, Java, a Flying Fox or Foxwing, and Nemo, a Bulldog bat. Yorick was their leader, despite being the smallest of the three. The reason for this was because he had the map to the tree, and knowing that the map could change at any second was often the cause of his rude and impatient attitude.
