The Curse Of Zeklos

Four Clans...
Five Dimensions...
Six sisters...
The Zeklos family has been the strongest and most powerful Vampire clan fit as rulers of the Vamperic dimension, even though it is merely just one of the four main royal families. Each clan had been striving for power for millions of years, fighting war after bloody war within their dimension. Never truly able to defeat the Zeklos, the other three clans decide to raise their white flags. Coming together they create a covenant to bring peace within the royals...
A millennium later, King Nicholae Zeklos comes forth with enrapturing news for this kingdom. His wife has given birth to twin baby girls, Crystala and Catalina. A decade later the queen gives birth to another baby princess, Celestia. It wasn't long after that for the queen to have a set of triplets, all girls. Kathryn, Irina, and Afina. The king both happy and devastated with his children he decides that the throne will be passed to two queens instead of having a king, since he wasn't able to breed a boy of his own. However one night, after contemplating it over, he becomes enraged with himself in not being able to give his wife a son, he turns to his daughters and curses them with a bond that runs deeper than blood.
The pain of one will be the pain of all.
One to fall shall they all follow at heal.
If death is to call, let the icy hollowness of loss be radiated through the body of all...
From then on, the six sisters shared a single life line, a single soul, a single pain.
The other clans found out of the King's mistake, leaving him vulnerable. The covenant was no more as the Ozera Clan ordered for the death of the six princesses; no more Zeklos would mean a termination to the line of heir to the throne, and without that, the Zeklos clan would seize to exist.
Thus the princesses flee, just as a war brews. Now it is to them to train and adapt in the Mundane dimension, for when they return, they shall take their rightful place in the foot of the throne.
