Universe M (Jenny Everywhere and the Lord of Hell)

Jenny Everywhere once shifted into a universe where she and Lord Grallyx were living ink drawings in the pages of the local counterpart of Laura Drake's demonology book, while trying to defeat Lord Grallyx, taking him along with her on a series of quick hops so as to retcon him into the fabric of all the universes she visited in the hope that, in one of them, he could be defeated.

This world turned out to be the lucky one: using a quill she'd kept from a different universe, Jenny was able to trap Grallyx by wrapping him in shift-preventing chain she drew into existence. She then shifted back to the universe she and Grallyx had started from, with Grallyx now trapped inside the version of the book in that universe. (PROSE: Jenny Everywhere and the Lord of Hell)
