Gates of Creation 

Wolff-Jadawin, demigod in Earthman’s guise, and Lord of the Planet of Many Levels, opened his eyes to see the symbol of the Master Lord, Urizen, floating below the ceiling.The summons of the Cruellest of the Universe-makers was direct and urgent. Jadawin’s beautiful wife had been abducted and held captive by the satanic Urizen In this uniquely amazing adventure, contrived by Urizen, Jadawin was required to enter the many-levelled universe that had been purposely constructed for his torment and possible destruction. Only through crossing the Gates of Creation could Jadawin redeem his bride, as he ventured through world after brutal world in an attempt to outfox the Master Lord’s diabolically booby-trapped planets.
