Character Movement
You can move a Short Distance or a Significant Distance. A short distance is always half as far as a significant distance.
You can reach targets nearby by moving a significant distance, or by moving a short distance twice. The effective range of physical movement while crossing difficult terrain, moving vertically, or swimming is halved. The effective range of physical movement while in low gravity is doubled. Magic and technology may be able to bypass the limitations of physical movement. You can also scramble to cross a significant distance in the time it would normally take you to cross a short distance. You cannot scramble in low gravity.
While in zero gravity, you cannot perform your baseline move or scramble actions. You must instead rely on magic, technology, or physics to move yourself around.
Info
If playing on a battlemap, a significant distance is 30 m (100 ft), or 10 hexes or squares. A short distance is 15 m (50 ft), or 5 hexes or squares.
