(Random world building #2: Souls) what do you think of them? what are souls like in your verse?
Souls
Souls are things the universe may create whenever it spits out something new into existence. They serve as a creature’s primary source of “consciousness” and its instinctive “need” to survive. Despite this important role, souls arent actually necessary. Many creatures possess consciousness and a drive to survive without having a soul at all. (The opposite is also true, with some creatures possessing multiple souls within a single body).
While most creatures cannot see souls, they are truly beautiful things. Souls appear as strange bundles of tangled light, constantly shifting and dancing as they slowly disappear. Eventually, a soul fizzles away into the universe, where its recycled into something else. When a creature with a soul dies, both the creature and its soul are recycled. It may not give the universe much, but it certainly gives more than you do.
Souls are also a semi-popular food source among certain creatures native to T.L.U., as well as some of the creatures that visit it.

Lone Souls
Sometimes, the universe creates a soul without creating a living body for it to inhabit. These are known as Lone Souls.
Lone Souls don't have an inherent limit to how large they can become nor do they serve any particular purpose or goal. They simply drift through the existence, shifting and dancing as they are gradually eaten down or recycled by the creatures or universe.
