In a world where multidimensional travel is possible, there comes a point where certain dimensions should never be bridged. The "Anti Realm" as it has been described it a world that all others have a faint connection to, as the excesses of negative energy start spill out and gather here, the energy concentrating into an oil like primordial goo. This gave rise to creatures known as the Anti, an intelligent animalistic force that feeds off of negative energy and emotions and wish to grow stronger to consume all the other worlds like an infectious hive.

The "Beast" Classification of anti are a quadrupedal monsters with candid and reptilian tendency, they are known for their voracious appetites and their swift motions that make them formidable hunters.
