Flagartha
(not to be confused with Flagistan)
Flagartha is the deepest known region of the recursive hollow flat earth in the furthest iteration. It is home of the Time Crystal.
The Recursive Hollow Flat Earth Model
Unlike pseudoscientific beliefs in a 'flat' or 'hollow earth', the recursive hollow flat earth cosmogonic model is true due to its recursive logical structure. The earth is flat but spacetime is curved, creating the counter-optical dyson sphere which we experience. Beyond this perceptual horizon the cosmos becomes periodic, resting inevitably on Flagartha.
Neo-Flagartha
Neo-Flagartha is a region consubstantial with Flagartha but new.
