Dimension:Corrosion Crystal

From the very beginning of all tales, the world was inherently unstable. Be it the mortal realm, the lofty higher dimensions or the abyssal lower realms, none stood firm.
 
Amid boundless chaos emerged exalted beings that transcended all universes, dimensions and realms, dwelling in the liminal space between existence and nothingness, bearing witness to all of creation’s chaos.
 
Then came the cataclysm that would erase everything. It swept across countless infinite universes, realms, dimensions, spaces and timelines, consigning innumerable histories and stories to total oblivion.
 
You, the one who commands this mortal vessel — will you stand against this calamity that plagues the world? This scourge warps all matter and devours every living thing; your arrival tore open Pandora’s Box and unleashed its blight. When the avatar of those exalted beings descends upon this world, every tale here will reach its final end.
 
Yet hope shall never fade. Even twisted monsters have forged ways to resist. The primal-pure will shall rise to confront this cataclysm of corrupt taint.
