Your aptitude magic is Sand. At the ritual to determine magical aptitude, which everyone undergoes at age 12, he, the Fifth Prince of the Empire, was judged to possess the Sand attribute. Three years later, deemed an incompetent who could only manipulate sand, he was expelled from the Empire and cast out into the desert, told to live with sand for the rest of his life if he loved it so much. He braced himself for death, convinced he couldn't survive in such a desolate place covered entirely in sand, but there he discovered the superiority of sand magic and even built a colossal sand castle. Realizing that what was once hell was actually a paradise for him, he decided to live a laid-back life in this desert. However, as he used sand magic to find desert resources and create oases, various races began to visit, and before he knew it, his settlement grew into a massive nation. His homeland, the Empire, took notice and launched an aggressive invasion, demanding everything. But his sand magic proved invincible in the desert, and the persistent Empire was repeatedly repelled by his sand magic, gradually declining. In stark contrast, the Sand Kingdom began to earn the respect of its neighbors.
