Ptaath's Hammer

A 17,000-year-old civilization awaits a divine prophecy toward the end of its days.
A mysterious alabaster Queen and an inhumanly strong stranger, black as night, are destined to come together in a doomed passion as their city and people are threatened with a terrifying conquest by an evil Immortal.
The Earth erupts and the seas rise as the dreadful triumph nears its pinnacle, and the powers of Heaven clash with Evil in a mighty struggle, and bring the prophecy to its foretold end.
