Rune Keepers: four heroes who protect the parallel worlds. They bear on their arms four marks, or Runes, four symbols for four heroes.
The bearer of the Triangle Rune was believed to be the last of his kind. Having to fend for himself and grow up on his own, he shaped to become a reckless being with dreams of adventuring. As he grew, he learned humility and selflessness, though he does not mind a challenge every now and then.
The bearer of the Circle Rune is initially an innocent, teenage elven boy with powers of channeling. But hardships soon came and sealed his inner light away, also nearly taking away his channeling powers. Through time, he was soon able to control his primal rage and rediscover this light.
The bearer of the Cross Rune is a raccoon who bears with him a lineage of thieves spanning throughout time. Though a criminal by code, he is a Robin Hood by any other name, only taking from those who have stolen. His adventures intertwining with his past allowed him to become a Master Thief.
Lastly, the bearer of the Square Rune is a teenage girl ready to take on the world. She always looks to the future instead of dwelling on her mistakes. Despite this, she learns that such a trait is sometimes not enough upon nearly losing her love, a living weapon who she accepted as his wielder and dedicated her time to helping.
