Shadow walkers. Also known as Spirit holders roam the Earth. There are only 10 of us, and I am one of them. The different spirits consist of
1) Red. Holds bodies stamina and supplies unnatural amount of it.
2) Green. The ability to move quicker and faster. This includes the ability to basically teleport due to the amount of speed gained.
3) Blue. The color blue signifies if you’re a spirit holder or not. The spirit holders have sparkling eyes, and non-natural abilities. And I say, if you ever run into us, we have some pleasant surprises for you. Oh, and dare I say that those were the only three basic ones. As a spirit holder myself I have four of these. These colors are called souls.
