Sabina Tiama Domina
The daughter and firstborn of Hyperius Tiamus Dominus, Sabina was the heiress of the Legion of Thunder and the Cloudlands. She served her father with devotion, and was known to be a cruel and demanding storm witch. She was significantly powerful within the realm of the arcane, supplementing the storm magic taught to her by her father with additional arcane paths in order to always surprise those who stood against her in either the battlefield or the Legion's courts.
As she grew older, she slowly became the face of her father, who preferred to stay in seclusion. Unofficially, she became an additional rung in the chain of command between the imperator and the praetor.
