An arm made of liquid darkness and deformed bones burst forth from the center of the circle. Followed by another. The stones around it crumbled like sand before the cursed presence that now rose up. Reality itself seemed to tremble, the air grew denser, and the runes still burning on the ground went out like candles before a storm.
From the hellish hole rose a creature that should never have existed. A demon. But not just any demon. An Arch-Abyssal, shaped by the hatred of a thousand extinct civilizations.
Its eyes were bottomless pits, mouths foamed where scales should have been, and beating hearts could be seen throbbing outside its body, pulsing in incoherent rhythms. Its wings, made of bones and veins, opened with a crack that echoed throughout the temple, knocking down columns and exploding doors with the pressure of the impact.
