The main real-world applications of space magic are to change the direction of gravity or reduce its effects. Theof Victory’s military use the antigravity form of space magic, mediated by large flight crystals. These crystals are expensive and difficult to make. In fact, “expensive and difficult” is a phrase closely associated with space magic.
The few space mages among the human population have blue stones set in their bracelets (usually sapphires, since they are well paid).
Time magic is, if anything, more expensive and difficult than space magic, and is little used. Extremely valuable items that might deteriorate over time are sometimes put in stasis boxes, in which time passes more slowly. It’s theoretically possible to speed time up, as well, but considering how difficult it is to do so, there are no practical applications.
There are no human time mages.
