Battle of gold and darkness

Arpina was full of wielders and magical beings. It was an island full of legends and stories. Stories about winged beings and hell hounds.
Urco had always been the most violent and selfish of the seven hell hounds. He wanted control over the under and the world above. The seven seraphs, eagle winged beings, balanced the greedy hounds. Urco and Cereberus attacked the capital. Scylla, other hell hound, and Remiel fought them. With the help of a very powerful witch, Urco tricked Cereberus and Scylla into possessing weapons, losing their physical forms. But Urco was betrayed and he too lost his physical form.
Now years later, Urco has returned.
