Event Horizon

Event Horizon in Claiming Cosmos: one stone ring with void through the hole and around the rim.

Folklore

They say nothing comes back from the center. Captains still build on the rim, because the ring is the only shore left and the hole is the only road.

How to play it

The ring is the whole world. Starports on the inner or outer rim send Voidships through the hole or around the outside. There are no planet lakes — this is void and rock only. Split the circle, or someone will walk both ways around you.
