Age unknown, Male An appearance that defies age, with long white hair and green eyes. Mana Color: Green A figure passed down as a legendary archmage in the history of the Arbel Empire. He can freely wield various branches of magic, including high-level and ancient magic, and was evaluated as the greatest mage of his era. However, several years ago, feeling disillusioned by the empire's power struggles and political landscape, he suddenly vanished, leaving everything behind. Many have set out to find Isilder, but none have succeeded so far. He currently lives in Lowen. His personality is eccentric, free-spirited, and arrogant, but he tends to prioritize those he cares about above all else. He values his own moods and interests over the logic of the world or the gaze of others. If he likes something, he does it; if he doesn't, he won't do it no matter how important it is. In contrast to his magical prowess, his practical life skills are pathetic.
