Working on a sci-fi project, similar to well known properties, in which real world road maps play a role, but need to justify them in world on a planet where people don't build on the surface.
I have entertained the idea of
- septarian nodules: rock formations that resemble roads.
- An extinct ancient civilization whose roads persist.
- laser projections showing 'safe paths'
None of these quite work. Does anyone know any other reasons why roads or road like formations might appear on a planet's surface?
The planet is a remote, outer rim space pirate haven loved also by the cartels for the presence of a rare mineral that is created by some of the local fauna. Said fauna prevent people from settling on the planet's surface, and yet there are 'roads' present. Desert in appearance, and made nearly inaccessible by an asteroid cloud.
