Kinetic Orbs are unseen objects in the Prime Series. They are to be used with Kinetic Orb Cannons for unknown purposes, though they appear to have been used for the transportation of supplies and as weapons. They are around a meter in diameter and spherical in shape. Because of the momentum caused by the force of ejection from the Cannon, and that there is little fluid friction due to their shape, the orbs are easily sent across great distances.
