This unnamed Dark Mage is one of the elite hunters serving the League of Darkness. He sits on a throne of obsidian and solidified nightmares in a lightless dimension, and sensed the ignition of a Sphere of Light the moment Moises awakened it.
His weapon is a spear of pure darkness that does not travel through space — it pierces the fabric of reality itself, targeting the exact frequency of golden energy rather than a physical location. This makes it impossible to outrun but imprecise: it destroyed Moises's home and killed his family rather than Moises himself.
His identity, true name, and rank within the League hierarchy beyond "elite hunter" are yet to be revealed.
