Frugal Wizard Multiverse
The Frugal Wizard Multiverse is an unnamed multiverse that is the setting for The Frugal Wizard's Handbook for Surviving Medieval England, any potential Frugal Wizard sequels, and possibly other stories. Cecil G. Bagsworth III, an interdimensional wizard, is the editor of the Alcatraz Versus the Evil Librarians series and A Night of Blacker Darkness, implying that the worlds of those books are accessible from the dimensions of Frugal Wizard and therefore part of this multiverse. The Frugal Wizard's Handbook for Surviving Medieval England was not written with any intentional connections to the Reckoners Multiverse, but connections might be added through The Apocalypse Guard.[1]
Concept
A person from one dimension can open a portal to another dimension that branched from their own at some point and travel "downstream" through it. People cannot normally travel upstream;[2] however, Woden, Logna, and other such beings have managed to travel upstream through several dimensions.[3]
