The Prismatic Core is a single gigantic power souce build into the Void Ray ship. Prismatic Core is used to power the flux field projectors. This device seethes with energy drawn from two realms: The Void, and The Storm. In combination these two energies form a self-sustaining reaction of terrifying potential.
As the Prismatic Beam is held on the target, more of the focusing array becomes aligned, and up to three individual power streams combine together. Over a few seconds the beam's intensity and power grow exponentially. Few enemies can withstand the awful power of the prismatic beam for long.
Normally the Prismatic Core is held in check by an arrangement of flux field projectors. When a Void Ray locks on to a target, the projector arms smoothly part like the petals of a flower. A complex array of warp lenses and phase-crystals works to focus the energies of the Prismatic Core into a ravening beam of destruction.
