The Endless
Before time itself, in the darkest corners of the early universe, the cosmos coalesced into a group of ethereal beings called The Endless.
These entities materialized into a physical state where they would hold a vast control over the very laws of existence. Nothing was beyond their reach or understanding. They thrived and prospered in every way for eons. But harmony never lasts.
The Endless eventually began to fight amongst themselves, eventually waging war against one another and creating The Eternal Relics. These extremely powerful tools could be used to bring everlasting peace or unfathomable destruction. As a result of the epic conflict, a hole in reality was torn open into a new plane of existence: Dark Space. A ruined battlefield haunted by extreme danger and chaos, it bred inconceivable horrors.
Eventually, only two remained: The Caretaker and The Devourer. The Caretaker was determined to save the ravaged universe while The Devourer vowed to consume everything for its own. The Caretaker was ultimately able to imprison The Devourer, finishing the fight. Unable to be destroyed but too dangerous to remain together, The Caretaker scattered them throughout the cosmos. Dark Space and its inhabitants would overwhelm reality if left unchecked, so The Caretaker sealed it away from the rest of the universe from the inside.
