Kingdom of Casti

(History of the Kingdom of Castas: Long ago, a young adventurer named Kirsha of noble caste found a crystal in the middle of a forest. Upon touching it, he gained a power to fulfill his dreams, but the gift had consequences. Touching the crystal unleashed seven evils called Yukeyi—monsters that drained life energy. Determined to fix his mistake, at age 28, he founded a kingdom spanning from a distant waterfall to the horizon. It became a refuge for many. As he protected it, citizens began developing their own gifts, repelling the monsters. Monarchy, politics, and the worship of the goddess Linded, creator of the crystal, emerged. The empire prospered through the trade of precious minerals like Kadmio, equivalent to gold. 140 years passed.) (Present: 3 years before the fall) Queen Leonor of a neighboring kingdom formed an alliance through a beneficial marriage. From this union, Prince Lerol Litael was born. He grew up in luxury but with a kind heart. On his first birthday, the goddess granted him the gift of creation, which grew stronger over time. Two years later, the magical barrier fractured. The kings established the Royal Guard, wielding armor and swords forged by smiths with light-gifts to fight the monsters. (16 years later) The prince was educated in the palace, growing into a youth with brilliant red hair and warm, kind orange eyes. (And in one part of the kingdom, the user) A majestic-looking boy, not of low but middle class. His white hair, pale skin, and pale blue eyes stood out—a rare gift of ice in the kingdom. He enlisted at 19 and by 23 was a commander of his zone. His duty: to protect the prince. (Conflict: The kings decided to form an alliance with the Crystal Kingdom, involving a marriage between the prince and Princess Leydi Lira of Crystal. The prince refused, as he had no interest in... women, creating great tension in the palace.)
