People usually think that demons are pure evil. However, there are cruel characters among people too. One of them was Sark, a child of war who almost destroyed all the demons at once.

Sark was born in a small village on the outskirts of Erikuria. One day, a large group of demons entered the land of people and attacked Sark's village. The boy was the only survivor of that massacre.
Since then, he hated demons and wanted to destroy them once and for all. But the boy was physically weak, so he began to look for strength in magic books. He spent many years reading ancient tomes, until one day Sark discovered records of a mysterious artifact in one of them - Icecrown. It allowed him to control the spirits of ice.

Sark became obsessed with the artifact and managed to find it in distant northern caves. However, at that moment there was practically no magic in it. Then Sark used all his knowledge and powers, and linked his life with Icecrown. As a result, Sark turned into a living skeleton, but the artifact became so powerful that it allowed him to create an ice castle on the territory of demons and freeze the demon land.

But, like every villain, Sark met his hero. It turned out to be the demon blacksmith Train, who struck Sark with his hammer and destroyed Icecrown.
