An odd name for an odd place, or places… time, or times… Wüdle Büdle is the dimension within and without all other dimensions. All time travelers pass through here for simultaneously every point in time and no point in time. Naturally, time is irrelevant in this dimension.
So, when a group of adventurers from different dimensions and different times with the same exact objective completely coincidentally arrive in the same general space in Wüdle Büdle, they find that they’re the only ones that can see that they’re in Limbo.
Them, and a mysterious silver eyed native of the dimension.
She begins leading them around the dimension on an adventure to get the hell back to their home planes, but maybe she has an ulterior motive for helping them? She seems to be the only native they find and wherever the unusual group goes, crazy monsters and a random Amish man in a Horse-Drawn Carriage seem to follow.
