Shirogane Renatus

Shirogane Renatus was an Alabaster Highborn that fell in love with the Pillar Flona Midsummers. Before Flona died in the First Core War, she defeated him and made him perform an Alabaster Oath. The terms of his oath were: 1. Stop feeding on the mortals, 2. Don't trouble the world anymore, and 3. the next Pillar, who will be taking my gemstone, please train her as much as you can, for the sake of my love. After her death, Shiro kept his promise to protect and mentor the succeeding Ruby Pillar, Pepper Eisler, until she matured. By the time Pepper completed her training under Shiro, he had become a living skeleton because of his abstinence from feeding on humans for many years. Pepper thought of him as a surrogate father, because she never had a proper family. When Shiro's life finally gave out and he turned to dust, she was the only person still alive to know his story. It was known as the only time Pepper ever cried in her life.
