The Pack

The Pack is a special group of mercenaries that deserted the school during the Great Divide. They are all mutants that are nomad for hire. These mutants all share the ability to partly/ fully turn into certain animals. Their leader goes by title: Pack Leader. This group is constantly at bay with the Shadow Mutations except for Dragoon. Due to this, the gaiaphage finds them a nuisance, but only one the way a mosquito annoys whoever they fly by. They go by their animal names.

Wolf (Pack Leader)
Wolf was logically thought of as Pack Leader due to his animal. It is unknown if there was a background story to it.
