The Players of “The Grey”, Become Sphere Makers.
A Sphere is a region of Elemental Influence that the Player creates.
Habitat and Mankind Cards are combined, to form an open hand in front of each Player.
A card entering the Sphere, must align with colors of randomly chosen Jewels.
Five places to lay cards are like Continental plates that form the Player’s Sphere.
Each card is crowned of a matching colored Jewel in what are called “SLOTS”.     Space Walker: Mankind's Exploration
