Gravity
The attraction of mass to mass; it holds atmospheres, orbits, and oceans in shape.
description
Gravity is the curvature of spacetime in the presence of energy and mass, or, in the older useful picture, an inverse-square attraction. It is weak compared with electromagnetism, but it has no opposite charge, so it accumulates.
Falling, weight, tide, and orbit on the map feed Gravity. The card keeps the force, not each of its costumes.
