Shadow

Shadow is the commander of the Tree Bark Regiment.

Background
Shadow self appointed himself as the rank "Lord", which later became "Commander". He create the idea of the Fire Tree for his regiment. When the Fire Tree was attacked by felids, they were driven out. Shadow led the regiment around the forest until he noticed a new colony of chiropters has moved to the mainland from the island further out from the coast.

Dusk's Colony
Shadow commanded the Tree Bark Regiment to follow Dusk's colony's activities for any chance to be given a home. When he learned that they were often under attack by felids, he told the colony that his regiment would provide protection in exchange for a home. Dusk's colony agreed and they moved into a neighboring tree. However, the tree was filled with angry birds that attacked the regiment. Shadow thought that Dusk's colony had led them into a trap. He took his regiment back to the colony's tree and demanded an answer.

Dusk's Recruitment
Shadow heard about Dusk's previous acts of courage that save his colony. He knew that Dusk's abilities would help out the regiment a lot so he asked Dusk to join his regiment. Dusk agreed and Shadow assigned one of his most loyal chiropters, Tark, to explain how the regiment worked.
