Pralaya has consumed everything - except for a magical reflection of Constantine Zatanna created. He then creates a projection of her, and they work to help the World Tree; the House of Mystery hid itself from Pralaya, and within its conservatory they succeed in contacting a version of Swamp Thing. Pralaya becomes aware of their existence and begins to drag them into her Void. John and Zatanna distract her so Swamp Thing can leap within her; she sprouts vines that fruit; this fruit bursts and releases the Justice League Dark! Zatanna explains that she'd sensed her copy of John in the House and devised this plan to reseed the World Tree and repel Pralaya. Returned to the House, Zatanna realizes the World Tree is gone. Creation must live, and both World Tree and Pralaya must await their proper cues. Then the House of Mystery begins moving, speeding towards Earth. It crashes there, and Constantine is standing outside. He did not seize control of the House, but he did answer a summons. Zatanna realizes her time with the Justice League Dark is over, and Constantine must assume control of the House. Constantine again feels at home...
