Simberro has been the name of several male nobles of Aesedra, though no Emperor has ever been named this. Most notably, Heir Apparent Simberro Rolle was the son and eldest child of Taian XVII Rolle, who was murdered in Xicomor during a campaign. His sister Bielana II Rolle took the Throne on Taian's passing and lived an unhappy life.
Another Simberro lived in the same era. He was the third son of Taian XVIII Rolle, and younger brother to Randith Rolle and Ospertine I Rolle. His daughter, Bielana III Rolle (named after his relative, the previous empress Bielana) acceded to the Throne. Simberro had been murdered by Makaeli rebels several years before.
