The Aboleth

This is the third multiverse.

The past two were born, existed for an eternity and then faded into the long dark.

Only a few entities remember the first two. The beings the Aboleth were are from the second age.

In that before time, the Aboleth's sun was old and it scorched their world frail. These people(?) retreated beneath the sea to hide from their baleful star. As the end of time approached the Gods gathered their faithful and departed beyond the veil to realms unknown. Those who remained were the atheist, agnostics, and libertarians who would not commit their souls to a God and these free souls were the last remaining as the stars winked out. As the end drew even closer the remaining Aboleth joined together, each an individual, each part of the whole. When the end did come they weren't afraid, they were together.

The third multiverse was born from the second, but not all that was old was new again. Some of the old remained. Some are called Old Ones who were beings too strange to die, some the dark tapestry, and others still the Aboleth.

The Aboleth came back because while the multiverse is light, energy and potential there has always been the dark. The dark remembers and it was the dark that cocooned and preserved the Aboleth.

In the third age light returned and the new multiverse was born. When worlds formed the dark could be found under and inside these places and as if thawing from a glacier the preserved Aboleth awoke from a timeless sleep, on the far side of oblivion, wanting nothing to do with the gods they no longer needed or feared.
