I'm so glad someone is asking about Lands. For my SBURB Text Adventure Game/Live Terminal Interface via Discord, I have 4 players who have fully entered The Medium and they "made" the following Lands (written by myself as "The Terminal" on the secret Terminal Discord):

Land of Crime and Neon (Pescia) Vibe: Corrupted Las Vegas with cyberpunk noir, neon lights, criminal syndicates, Hope-as-vice mechanics, underground VIP clubs, and lore puzzles hidden in ads. Land of Tomes and Tides (Deaper Xauric) Vibe: Haunted library archipelagos with ocean tides lapping at endless stacks of books, knowledge as a physical flood, mystical ink currents and self-writing tomes. Land of Glass and Signals (Rosie Riviter) Vibe: Crystalline towers, radio beacons, and light-as-electricity puzzles, the whole place behaves like a massive optical network waiting to be re-routed. Land of Fracture and Filaments (Broket Dunced) Vibe: Splintered cliff-mazes laced with hanging power cables and spider-like consorts, Doom vision and Rage leaks between cracked dimensions.
