Ratreyfian Underworld
From Jenny Everywhere Wiki
The Ratreyfian Underworld was a portion of one universe's Hell. It was ruled over by a demon called Lord Grallyx and his legion, until Grallyx was summoned to Earth by Laura Drake and Jenny Everywhere, whereupon he tried to wreak havoc only to end up trapped inside a demonology book by Jenny.
