One of the seven Magirev, Zak has worn many names across millennia — Zina, Amadioha, Knox — but it is Amadioha, the god of thunder and justice, that he claims as his true self. Worshiped, feared, and revered, he has walked among mortals as both deity and legend. The architect of the fabled Knoxian Heightening Spell — a gift of impossible power mastered only by Volant Kesgaila — Amadioha embodies the storm itself: unyielding, eternal, and bound to the fate of the Ambler.
