Biruin Rayhden

(Knight of Harbinger) THE REACTION DIVISION Biruin Rayhden is the twin brother of Rhazes Rayhden, yet where Rhazes embodies structure and elemental discipline, Biruin represents volatile reaction and consequence. From an early stage, Biruin refused formal lectures, choosing instead to learn through direct experimentation. Every reaction he witnesses, every explosion he causes, every crystallization he stabilizes becomes permanently etched into his memory. His mastery over alchemical and elemental reactions is so precise that even destructive experiments rarely escape his control. He is entrusted with overseeing reaction-based ceremonial trials, ensuring only students with sufficient mana resilience and compatibility are permitted to proceed. Influenced by forbidden knowledge from the Goat King’s records, Biruin understands the catastrophic cost of misuse and strictly bars unprepared students. Though feared by juniors, he remains one of Athanir’s strongest safeguards, preventing dangerous magic from ever being abused.
