Without warning, the crystal shattered.
A deafening crack rang through the church, followed by a surge of dark energy. From the remnants of the crystal, a torrent of miasma burst forth, swirling and writhing like a living entity. The thick, black fog twisted and spread with alarming speed, engulfing the entire church in moments.
The miasma flowed outward, spilling through the cracks in the walls, creeping like a shadow through the dungeon's twisting corridors. It moved with purpose, seeking, searching, until it found the newborn Autumn Toads, freshly spawned in the dungeon's lower layers.
The first of the toads to encounter the miasma froze in place, their large, bulbous eyes widening as the dark fog enveloped them. They croaked in confusion, but it was too late. The miasma seeped into their flesh, twisting and warping their bodies. Their once vibrant colors dulled to a sickly greenish-black, their eyes glowing with an unnatural, malevolent light.
