Xanthe Terra — Frank A. Ruffolo

1300 years after the Great Judgement, mankind is still making the same mistakes. As humans continue to tamper with God's creations, they accidentally terraform Mars into a hospitable planet, and in the process, awaken the beasts that destroyed that world's ancient civilization. These bizarre creatures now threaten to wipe out the current citizens of Mars and Earth-with eager help from the Evil One, Satan himself.
