A long time ago when the world was still young and beautiful all creatures lives in peace until the Shadow Walkers wanted to rule the world. They killed all leader and take things into their own hands. After the death of the their loves ones, the Shape Shifter wants revenge and they too started war with SW. Many creatures who were caught between the two Clan tends to get killed, many has left and hide within the forest. All creatures knew there are only Six Angels in the world that can give them the power they desire. Their pure blood can give lifes to those who die and cure any kind of sickness. Having to search through the world for these Six Angels wasn't an easy job for anyone, since they can change into any creatures on land as long as they touch them once. They're wings are the brightest when they fly, no matter where you are you will see their wings glow. They get sick when they see death in front of their eyes, they can't stand the smell of blood and if they were to be aparted from one other, the Angel that is alone starts to get sick.
