The Feywild and Shadowfell

How Musto operates and how it came to be is unknown to those who live there. It is clear Musto is of the Prime Material Plane. Those few familiar with the workings of the Multiverse have long assumed that if Musto is of the Prime Material, then it must have a Feywild and Shadowfell version of itself. However, no entrances have been found, and attempts to access those planes do not have the expected results. For a long time, many thought these realms simply did not exist in Musto.

About 20 years ago, creatures of the Feywild and Shadowfell began appearing. Typically coming from deep in the wilds, creatures from these planes have no recollection of their entrance or what came before finding themselves on the Prime Material Plane. They have no memory of the place they came from, though they all seem to be drawn to various locations in the Musto, many unable to resist the urge to find a thing unknown.
