Dark Souls 2: Crown of the Sunken King is a paid add-on for an action role-playing game with a third-person view in a fantasy setting. In search of the Crown of the Frozen King, you travel to Shulva, a city hidden somewhere in the depths of the Black Cleft.
This city was built by the Frozen King when he discovered a sleeping dragon here. The people who began to live here revered the dragon as their sacred treasure; they sang songs to Sin to keep him asleep. One day, the Knights of the Dragon's Blood found out about this place. They believed that fresh dragon blood would help them understand the very essence of life, so a siege was organized on the city. During the conflict, the commander of the knights, Ser Yorg, killed the Frozen King, and also tried to appropriate Sin's blood. But as soon as he pierced the dragon with his spear, Sin awakened and exhaled the poison that had accumulated in him. Because of all these events, the city was destroyed and everything in it was saturated with poison. But the Queen, the child of Darkness, still lives here, and she still sings songs to the dragon.
