"On the dreary Zandaran plains, Kai-Osuro's Royal banner fluttered in the wind. The wicked Serpent King Zahak's troops fled like a flock of sheep afraid of spring's lighting.

With the holy sword Ruknabard that could cut iron in two, forged from fragments of the sun, and on his favorite horse Rakushuna, to those who saw him, Kai-Osuro truly earned his name of Supreme Ruler of the World.

From the skies, the sun separated the Earth into two and the World above ground was united in one Kingdom.

Who could follow the destiny of that kind of hero..."

The legend followed that Kai-Osuro entombed his rival, the Snake King Zahak, in his subterranian Kingdom under Mount Demavand, sealing the intrance with Ruknabard itself.

This is how Pars was born.

It is believed that only one of direct descendance from Kai-Osuro can wield the sword that still sleeps in a crypt in the mountains.
