Vijilant Semi Serious Sims

I make board games and wargames set on and in The Shell - a hollow planet the size of Saturn. I also make random other stuff from time to time.

On the Shell, a thin atmosphere fills sparse valleys the size of continents. Up on the airless shelf gravity reaches a crushing 3g, but if you travel down, past the seas and cities where gravity feels normal, through the caves of the Sahn... suddenly there's nothing.

A vast cosmic vault the size of 100 earths stretches below you. Storms rage and flash in the depths as you drift weightless. Humid, warm air fills your lungs. Collosal shafts of light beam through the haze, fractures in the shell allowing the sunlight in.

What lives below?
