The Source is the center point for the orbits of every universe in the multiverse. From it, Source-energy flows like light from a star, absorbed and reflected by the universes orbiting it like so many planets. Source-energy can, hypothetically, take many different forms. Just as a planet's atmosphere and distance from a star changes the shade its light may take, so may a universe's orbital path and distance from the Source change the form Source-energy takes. In the universe of the Sith Imperium and those parallel to it, Source-energy is expressed as the Force.
