The Contemptible Cube of Quazar (An OSR One Shot)

Quazar, an Evil Wizard, has landed his cube-like stronghold on the World of Eris. He is trapped in his inner sanctum until he can be freed by the four sacred keys. In the meantime, the uncontrolled denizens of his fortress venture forth at night to feed on the locals and plunder the immediate vicinity.

Somebody has to put an end to the MADNESS and MAYHEM!!!!
Pre-gens will be provided.
