Tristaria Zelona Seithe, known almost universally by her nickname and regnal name Aria Nikina, was a half-Human, half-Tantaari bastard daughter of Genera Seithe who rose to overthrow her father and become Queen of Daispin. Pledging her planet to the Golden Empire, Aria herself became a Centurion of the Order of Keltrayu, famous the Empire over as the "Scourge of the Witch Queen" and "the Breaker of Tyrants".
