The Force is a universal energy force that binds all life together. Over millennia, sentient beings learned how to harness the Force to use as a tool and as a form of supernatural sense.
Many sects have arisen with the goal of utilizing the Force and studying its abilities, often with different intentions in mind and often dedicated primarily to either the Light or the Dark Side. The most famous and influential of these sects are the Jedi Order and the Sith, who have been at odds since their creation.
Within the Force, there is the Light Side and the Dark Side, as well as other philosophical views of the Force.
