Back in the days of turmoil within the lands of Aridell two herds lived. The first was of common equines, all living together in love and harmoney. The second of demon equines, raging and ransacking the lands. At the fall of Demon's empire the members had nowhere to turn to without their leaders guide.
So the two herds desided to have a treaty, where each would live together in peace. A meeting was held, and a plan was made. They would have a bonding mateing. A stallion from the darigans and a mare from the common unis would mate and bare a foal that would bring both herds together. The two were chossen, but not by will. They both hated and dispized the other, but the herds pressure was great, and soon a foal was conceived. Both herds were shocked at the tiny filly as she stared up at her two families.
Her left side resembled greatly her father with his dark colors and batlike wings, yet the other side was as her mother, golden and bearing the wing of angels. But all was not well. This created a great conflict for each side wanted to raise the child as their own. For her first year of life she was constantly pulled from one end of the herd to the other, till the day came when she was old enough to choose for herself.
The poor mare was so filled with conflicting lies told to her about each side that her mind could not handle it. And they say she went mad that day, her mind riping in two. Spliting into two completely different personalities.
Her left side, which chose to call herself Kalis, was like her father, dark, foreboding and bitter, while the right, called Stana, was sweet and good and kind like her mother. Neither side could agree on a family, so she chose to join neither, and left her bewondered parents that day to set out on her own, but the conflict that caused her mind to rip did not wear away. I remained and still the mare is of two concious states, and both argue and bicker with the other, just as their familes had. But, this is all she knows, and for all she's concerned, it is the way things should be.

Alone at Last...
