Her tentacle roots had already pierced the planets core. devouring it. And using its energy to transform her into a new being. Becoming a new core.
An embryo of indescribable malignity that pulsed and beat to the rythm of a newly formed chaotic heart. Every pulse sending ripples that counted down to this worlds imminent destruction.
Like an embryo growing inside an egg. Devouring the nutrient rich albumen as it evolves. So too Cosmos grew. Her from feasting upon the inner layers of the planet as she swelled outwards.
Pushing the outer layers apart as she grew faster then she could absorb them. Until the planets very crust has become naught but an eggshell. A hollowed brittle crust that housed her metamorphosis.
With a final satisfying explosion the shell shattered into a billion tiny pieces as Cosmos flexed her new form. Its death thours heralding the arrival of a new cosmic entity. (a new world had been born) A fleshy, chaotic amalgamation of Chaos made manifest. A new celestial body. Bigger and better then the old one. Exposing its naken, newborn perfection to the universe.
And like a newborn, she immediately began to devour the remains of the eggshell that has housed her metamorphosis.
For not even the hollowed out, soulless rocks would be allowed to escape her. Not one grain, not one speck of dust.
Not a single atom would be allowed to soil the universe. For even though her new core burst out from the remnants of that filthy dead world.
The remnants of that eggshell would be sucked down into her gravitational pull. Hand upon her Terrestrial being , and be devoured.
Every last atom corrupted and violated beyond recognition. Until its place in space and time was to utterly torn asunder that it could never have been said to have existed at all.
Only Now would Cosmos ascension be complete.
Now. Truly noting remaied of that filthy pony world. It had all been erased from existence, never to be again. Never to have been.
A hole would have been punched in the void where existence has seized, were it not for glorious chaos rising in and filling that hole of existence. Outgrowing it, overflowing it with a everchanging ever growing amalgamation of almighty Cosmos.
