The Abyss

It goes on forever... none ever return from it's depths. It is the very face of destruction, as it slowly eats away the plane of Mascotia. Fortunately, new matter always enters Mascotia via wormholes and visitors. The Abyss is simply Mascotia's way of recycling the old. Where it goes, none know. It is thought the Abyss has devoured hundreds of gigantic regions over time - regions that nobody can even remember. The area in which the Abyss is all one sees is referred to 'The Edge Of The Paper'. Nothing from here on out. Luckily Mascotians migrate to avoid the abyss, so no mass groups of Mascotians have disappeared with this as a cause.
