Ragnarok

Ragnarok
A Ragnarok is somewhat of a judgement day for a supernatural place. It usually occurs when a major figure dies, or when a substantial amount of damage happens. In the Eighth Book of Prophecy, it is written what will happen in almost all Ragnaroks.

Hell
When Taynakhulat dies, aged roughly 1,000,000 (the lifespan of a Hell Ruler), Hell will suddenly fall into a state of chaos. First, the Fields of Limbo will shrivel into a desert, killing Bendoculous and Yendoculous if they have not died earlier. It will also kill all Hell creatures in it, and shatter the souls of everyone caught. Next, the Cliffs of Hell will crumble away from the hardening desert, and crash into Upper Hell. This will destroy at least Pain, Heck, Hell, and The Fields of Punishment. Directly after this, Upper Hell will lose its supernatural stability, and fall to Middle Hell. This will cause a chain reaction, each iteration deadlier and heavier than the last: Upper Hell crashes into Middle Hell, creating the Mound of Hell's Ragnarok, then that crashes into Lower Hell, the M.H.R. then falls into Cold Hell, which smashes into Castle Island, which finally sinks to the bottom of the Acidic Depths. Most every layer of Hell will be destroyed, and 99.9% of all living creatures in Hell will die. The Final Hells will be spared, however. Unfortunately, once Heaven gets the disturbance from Hell's destruction, it will send another Ragnarok across it. This will collapse the support of The Edge of Infinity, shattering The Dark Tomb and unleashing the ancient god Darkani.
