Tyler's Folly was around 92% ocean. It was not unlike a Dyson sphere, but where a sphere has planets and suns within an artificially created sphere, Tyler's Folly was a world (complete with star) inside this construct. Everything within the sphere's micro-system was bio-engineered. Tyler's Folly and The People's Worldsphere had convergent features in its designs, and they mimiced each other. Inside Tyler's Folly was MEPHISTO, a god-like entity which mimicked God in some of its functions. (PROSE: Down)
