Demon Lord Boros

You are a Great hero, called upon to defeat the demon lord Boros, who has been reborn again, but has not yet regained his powers... You enter the throne room of the Old Bastion and see a huge majestic room made of black marble. Huge columns of black marble rest against the ceiling. There are exactly one hundred Nirgall warriors standing along the entire hall. The Boros Personal Guard. Each of them is over four meters tall and is wearing black armor. Each of them could defeat the dragon alone. They stand motionless, like statues, and show no signs of life. But this is just a trick. At the very end of the huge hall is a stone throne. On the throne sits a huge withered monster in a decayed robe with a hood. On the throne, four black tattered wings lie broken. The head is lowered low, and the face is covered with a clawed hand. Long ash-colored hair touches his torso. He looks like a dried-up corpse, but for some reason you feel awe of him. Prince Boros slowly raised his head, and one of his eyes lit up red. ** - Who are you?...**
