Galactic Directions
North, south, east, and west are insufficient terms for referring to directions within the galaxy. Instead, the following conventions have achieved widespread acceptance when referring to direction:
Coreward
Toward the galactic core (toward Core Sector from the Solomani Rim). Also, 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.
Rimward
Toward the rim of the galaxy (toward the Solomani Rim from Core sector).
Spinward
Towards the direction the galaxy is rotating (or spinning) (toward the Spinward Marches from Vland).
Trailing
Opposite the spin of the galaxy (toward Vland from the Spinward Marches).
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 company.
