The Skurge - organized, humanoid creations of the Entity - are the most intelligent form of the Strain. Derived from the primal patterns of the Strain's victims, they possess a society that resembles a dedicated military force and are driven to wipe out the imperfect life forms that infest their world. At the urging of their master the Entity, they seek to replace all non-Strain forms of life with the true perfection of the Skurge - and take the Entity's revenge against a wretched and imperfect universe.
The Skurge are tall humanoids whose bodies are composed entirely of the Strain. Their skeletal structure projects outside their purplish-blue skin, and their physical forms exude a miasmatic cloud of Strain particles that can be infectious.
