Crundle is a planetish-place at the center of the Crundleverse, a cesspool planarverse that resides beneath Everything Else, formed and sustained by the mingling of magical energy that trickles down from every possible reality. As such, the Crundleverse is a nonsensical realm of giant tarsier gods and sneezing trees, among other denizens. Should you ever find yourself in this peculiar pocket universe, the best way to survive is to simply sit back and enjoy the weird.
Fixed Crundle, the only region of Crundle that is even remotely grounded in reality, is where we will begin our journey in this strange realm. As one moves further from the fixed center of Crundle where distance and direction are constant, one finds a steadily increasing tendency of the world to spontaneously rearrange itself noncatastrophically at random, the upshot of which is that you will never arrive at your intended destination except by pure chance.
