Will

A Will is a cosmic species that holds control over what lower-specimen call The Force. If they were known about, they would be considered to be the most powerful beings in The Galaxy, since they pretty much literally are, and both Jedis and Siths are technically powered by them.

Culture
There are currently three factions of Wills that are known of. The Wills that control the selfless Light Side, the Wills that control the edgy Dark Side, and the nefarious Wills that control the twisted and sickening Green Side. As a result of their boredom and being able to do anything, the factions started playing an on-going 10,000 year game of cosmic chess to see which faction of Wills could take the most control over The Galaxy.

Abilities
Wills are the most powerful beings living in The Galaxy and have the power to do pretty much anything they want, though they cannot harm each other directly. However, they are not omnipresent and have to manually fly around locations. Luckily, physics don't care about them so they're able to go as fast across The Galaxy as they'd like.

Because of the fact they are cosmic beings, lower life forms can't actually witness them unless they want them to.

Trivia

 * It is rumored that Wills can be imprisoned into bottles and made into personal servants, but that's ridiculous! Why and how would they ever allow that to happen?
