When Quadrillionaires get bored, you get The Grand Maze of Titan.
Terraforming robots turned the entire moon into a mind-bogglingly complex global maze.
And not just on the surface. The entire moon was permeated with tunnels and passages.
For years, brave adventurers would compete to solve the maze.
But a moon-sized maze is simply impossible for a human to solve. Not enough water, food, oxygen, energy, and time.
Drones and robots now swarm through the passages, mapping their routes and trying to work out a solution.
They rest on the surface, charging themselves before another dive into the twisted darkness.
