Derrick Redbat, a middle-class noble of the historically distinguished yet politically peripheral Redbat family, served as Ariel Anemoi Asura’s advanced-ranked guardian mage before Fitts. As the third son denied inherited influence, he forged his path through merit, graduating with top honors from the Asura Magic Academy. A pivotal encounter at a royal banquet—sparked by Ariel’s stirring speech echoing the ideals of her ancestor Kaunis Freean Asura—convinced him of her capacity to reign as a monarch cherished by the people. Accepting his father’s counsel, he joined Luke Notos Greyrat as her guardian, blending shrewd pragmatism with a sharp grasp of the kingdom’s fragile politics.

Criticizing the nobility’s decay and alert to looming external threats, Derrick drilled Ariel in statecraft, undeterred by her fears of assassination. His resolve stemmed from unwavering belief in her necessity to the realm’s survival. This dedication culminated during the Teleport Incident, where he intercepted a Terminate Boar’s assault on Ariel within the Silver Palace. Mortally wounded yet relieved by her acknowledgment of his loyalty—a contrast to his assumed disdain—he implored her to claim the throne with his final breath. His death coincided with Rudeus Greyrat’s unforeseen intervention, allowing Derrick to perish grateful, entrusting Ariel to this mysterious savior.

His legacy endured through Ariel’s hardened resolve to rule, Fitts’ inheritance of his guardian role, and Rudeus’ subsequent efforts to bolster her cause. Across timelines observed by Orsted, Derrick’s fate remained fixed—a death sealing Ariel’s destiny—though alternate paths hinted at his potential as her reformist prime minister, a testament to the enduring weight of his ambitions and sacrifices.
