Character from Overlord by Kugane Maruyama
The greatest human magic caster — a 200-year-old court wizard who devoted his life to magic, then betrayed his emperor the instant he sensed a being who had achieved what he never could.
Fluder is the strongest human magic caster in the New World — able to cast up to 6th tier spells, which is the documented ceiling of human ability. He has spent 200 years trying to break through to the 7th tier and beyond. When he sensed Ainz's aura — a being who had mastered magic far beyond anything Fluder had ever conceived — he betrayed the Empire without hesitation. His loyalty was never to Jircniv. It was to the pursuit of magic. Ainz offered him the path forward, and Fluder fell to his knees weeping. He is a cautionary tale about what single-minded obsession does to loyalty.
Elderly wizard with long white beard and robes befitting the Empire's highest magical authority. His eyes burn with fanatical intensity when discussing magical power.
