Mars, as a general rule, is dry as hell. The exceptions are minimal. The architecture takes this for granted. That was a mistake.

When a tropical storm threatens to engulf the whole planet, the last survivors of a dilapidated colony have to find a way to weatherproof their home.

Instead of doing that, they sacrifice some people to the devil.

Cyclones of Mars is a short story about staircases. 

It's approximately 5161 words exactly. 

It has illustrations. 

Trigger warnings for human sacrifice, water, corridors, drowning and vague, poorly-defined satanism.
