A downloadable TTRPG addon

Buy Now$5.00 USD or more

The second in a planned set of modular, pamphlet-sized rules expansions for the Rainworld TTRPG.

Beneath New Shenzen lies the Gyre: an expanding labyrinth of contested turf which, technically, shouldn't exist. Space is power; and so the greatest power lies with the people who control the twelve Diggers, reactivated early-stage colonisation tunnel boring machines.

Gear, information, and expanded character options for Homunculoids and Mutts!
