Primaeth is a material that comprises the material body inhabited by a Prime Entity that retains destructive and magical properties. When it manifests materially, its usually uses their preferred Avatar. The bodies are discarded when too damaged to function. These pieces are what is left on the battlefield.
Pieces of Primaeth can animate, twitch, release power or energy when within 10m of either Entrophy or Equitas.
This type of base material is comprised of Primaeth, and can be worked into many items, depending on the source of materials from the body.
