Four hundred years before Carter's arrival on Mars, while Princess Dejah Thoris is on an archaeological dig, a young Woola discovers an ancient First Born artifact - one that harnesses an evil energy! Centuries later, the Earthborn warlord and his loyal pet recover the device, only to see its corrupting influence wash over the Red People of Helium. The escalating chaos culminates in the single most difficult challenge Woola has ever had to face: the decision whether or not to protect John Carter. Will the fiercely devoted calot resist his strongest instincts to save Barsoom's champion - or pay an infinitely worse price?
