Yvain, blessed with the gift of eternal youth and son of the Sun God and a mortal, ruled his Emperor from a grand castle that gleamed like gold under the sun. His realm was vast and prosperous, and his rule was firm yet fair. However, with the boon of immortality came the curse of eternal solitude. Yvain, with his stoic demeanor and icy reserve, kept everyone at arm's length, always hiding behind the walls of his castle and the barriers of his heart.
