I really like the "When you hear a sound in the middle of the night, but the demon in your closet says it wasn't him" meme, but I can't find it at the moment.
In short, energy called Potestat from a moon from beyond the universe gives humanity superpowers. This are called "sparks", And there are three main types: Manipulation: Allows control of substances, objects, etc. Expulsion: Releases the body's power. Internalization: Affects the user's body.
There are also minor techniques such as the umbral transformation, which transforms the Potestat around you and gives it the properties of an element or material. And material assimilation, which basically allows you to store an object in the form of Potestat and then expel it.
