Force Affiliation

Although Force powers are not inherently good or evil, they are generally used by one side or the other with such frequency that they are commonly associated with that side. There are three affiliations that Force powers tend to fall under:


 * Light Side: Light Side powers are generally those used for protection, increasing physical and mental capacities, or used for defense. They can also inspire and increase the resolve of allies. Certain Light Side powers can also be used offensively, but do not directly cause physical harm.


 * Dark Side: Dark Side powers are those used to harm, debilitate, or kill. Some are used to benefit the user personally, akin to the powers of the Light Side, with the difference being that these are used at the expense of another individual. Continuous use of dark powers has been shown to have a physically corrupting effect on the Force-user due to the body's inability to handle such power for long periods of time.


 * Universal: Universal Powers are generic Force techniques which are associated with neither side of the Force. Almost all Core Powers also qualify as Universal Powers, but many of them are uncommon and not an integral part of basic Jedi training.
