The Force is a main upgrade to the ship - you can get it from Power Gem.
The Force is a piece of Bydo flesh. It has characteristics of both a life form and a mineral.
The growth process of the Force
By absorbing a certain type of energy, it undergoes a three stage transformation. When struck by a beam, a catalytic function causes the beam to change its form. Against the Bydo, the purest form of energy was extracted from this piece, and converged into a ball-like shape and manipulated through a control rod. The name "Force" implies both a physical and mental power.

Force Control Rod
Four rods are needed to control the Force. Each one organically combines with the energy inside.
