The Nightmare's nonexistent heart began to thunder as Balance brought them to the First Pit. It was created before time was even a concept, before life existed, before death existed. It was created to hold back Abominations, Horrors, Monsters and an endless swarm of Creatures whose very existence proved a threat to Creation itself. They had been sealed away in the First War, the war between the Creators and these Aberrations to Existence, and they would remain there for all Time. They were locked away for if they ever got a microschism of freedom, all life in Reality would surely perish.
