This world is connected to :
Destitute: a nightmare of the Nothing
The true Psychopath, and pretty much every story starting with "The true Psychopath"

The Psychopath exists in Equestria, however strange it may be to others. He can also reach other versions thanks to the World of Illogic, but even he has to use a map to get around his Equestria. Here, he'll tell all about this Equestria and the lands that exist beyond it, and the territories within it. He'll speak about the Jarred breach in the forbidden zone of the Seaponuvian ocean. He'll speak all about the strange new land, the Nyubet, in which lives a terrifying creature that none can trace the origins. He'll even talk about the city of Dissirva within the Dissirvian mountains, and its proximity to the borders of Equestria, as well as their relationship with the griffin kingdom.

If you're lucky, he might even tell you about a secret continent which has been affected by the energies of the Nothing, and what lives there.
