Directions, Galactic: North and south do not work when referring to directions
within the galaxy. Instead, the following conventions have achieved widespread
acceptance when referring to direction.
Toward the galactic core is coreward; away from it, in the direction of the rim, is
rimward. In the direction in which the galaxy is rotating is spinward, while the
other direction is trailing.
These directions are in widespread use in describing Imperial features and
businesses. For example, the Spinward Marches is a sector at the extreme spinward
fringe of the Imperium; Rimward Lines is an important interstellar transport
Finally, within the Imperium, the term coreward is also used to indicate the
direction of Capital, the Imperial core. There is some potential for confusion if the
term is accepted out of context.
