These circular passageways are lined with lights, white cushions and soft but strong loops of cloth. There is no artificial gravity in the halls (and the gravity is reduced to zero, even when the ship is in a planet’s gravitational field), so characters who cannot propel themselves (such as Nepleslians) will have to pull themselves along using the loops. Some of the cushions (which are labeled accordingly) are removable and contain lockers of environmental suits, medical kits, and other supplies behind them. Passages are approximately 2 meters in diameter. Eating or drinking in the passageways is forbidden.
