Famous Orson Scott Card Quote
From now on, you forget about gravity before you go through that door. The old gravity is gone, erased. Understand me? Whatever your gravity is when you get to the door, remember -- the enemy's gate is down. Your feet are toward the enemy's gate. Up is toward your own gate. North is that way, south is that way, east is that way, west is -- what way? They pointed.
