The strange dark stain in the air wavers and then grows solid. The peak of the ziggurat is restored, and affixed to this peak is a fifteen-foot-tall, three-foot thick trapezoid-shaped pinnacle of black rock, ten feet wide at the base and five at the peak. The monolith of stone shimmers and vibrates with waves of necrotic energy, and something strange and horrible seems to writhe inside its nearly opaque interior.
Suddenly, a brilliant red wall of scales fills your view, and there’s a terrible sound of crumbling stone. In an instant, an enormous red dragon is winging away to the north. The spire’s peak is in ruins, and clutched in the dragon’s talons is the monolith. The vision fades, and the dragon and its prize are gone.
You discerned the following:
-The ancient red dragon was the legendary Dragotha. According to legend he lead the assault of Aerenal during the Elf-Dragon wars.
-The shapes writhing inside the monolith seem to be made of worms arranged in the shape of an enraged face.
