Before their eyes the Temple of Karsis had transformed. Now a black stone pyramid rose into the sky, growing still. A massive portal raged at the top and something huge loomed into view. Disgorged from the portal directly down onto the flat pyramid top was a gigantic tentacled, primordial monstrosity. The twenty-foot-high thing wriggled its ropelike tentacles and four more portals instantly opened, one at each corner of the pyramid. Lesser elementals of all types began to stream through. An invasion had begun.
