(Name translates directly from ancient Egyptian as: Strong Protector, the Hidden One.) A mysterious shaman appearing without regard to wheres and whens, upon the divine bidding of other Realms. An entity of legend, belonging to a legendary and ancient sect.
For a futuristic grim gory setting. Probably powered by some kind of dilithium battery or something similarly awesome. Anyways, basicly a big drill sticking up from a hilt that you primarily use for skewering enemies painfully and drilling through armor.
