Protective of it's little sister, Redshift, Blueshift is almost always at her side to try to protect her.
Pack History
Blueshift and Redshift were from a pack facing a serious prey shortage. Their pack and a neighboring pack became super competitive over food, until the other pack ambushed them. Blueshift and Redshift, both malnourished and starving, were separated while fleeing. Redshift has no memory of how exactly she was killed, but Blueshift might.
