Gran Kain was a free and uninhibited god. However, he made a very great mistake by seducing Shilen, his eldest daughter. They conducted an affair, avoiding the eyes of Einhasad, until Shilen became pregnant. When Einhasad found out, she became enraged. Stripping her daughter of her position as water goddess, Einhasad ordered Shilen banished from the continent. Gran Kain turned his back on the situation, and Shilen was left to deal with her fate alone.

While pregnant, Shilen fled to the East. Deep in the middle of a dark forest, she gave birth -- cursing Einhasad and Gran Kain with each excruciating labor pain.

The babies born of Shilen's horrible labor bore the despair and anger of her curses and became demons. Among them, the strongest creatures were called 'dragons.'

There were a total of six dragons born with curses against the six gods. Shilen was filled with wrath towards Einhasad who banished her, and towards Gran Kain who seduced and then abandoned her. Gathering the strength of her children, she created an army to punish the gods.

The strongest dragons were ordered to be at the front of the army of demons to fight against the gods. Hearing this, Aulakiria, the dragon of light, looked at Shilen with sad eyes and spoke.

"Mother, you don't know what you are doing. Do you really want the eternal destruction of the gods? Do you really want your father, mother and siblings to fall down on the ground in pools of their own blood?"

Her appeal did not change Shilen's mind.

At last, the demons invaded the palace where the gods lived, and a fierce battle began. The six dragons destroyed everything in the gods' palace. Even the gods were intimidated by the incredible power of the dragons. The battle seemed destined to continue forever. Yet, if the war did not stop, the world would cease to exist, and all living things would be annihilated.

Numerous god's messengers and demons were destroyed or vanished. Every day there was thunder and lightning, as strong forces clashed violently in the sky. Giants and the other living creatures of earth trembled as they observed the terrible fight in the sky.

The fierce battle continued for several years, and eventually the balance gradually tilted towards one side. In spite of suffering many injuries, Einhasad and Gran Kain, had stronger powers and destroyed many demons.

The dragons kept fighting, though they were deeply wounded and riddled with scars. Their fatigue became more and more apparent. After a time, it seemed like the war would come to an end with the extermination of Shilen's army. In the end, the dragons spread their wings and flew to the earth to escape. The surviving demons followed. The gods wanted to kill the retreating army. However, due to their own injuries, all they could do was watch as the dragons and demons departed.

As Shilen's children perished one by one and lost the war, Shilen could not stand her sadness. She invented The Underworld and ruled over it.
