Blind Ruler of Ta'tarus
Master Er’bus was once apprenticed to Master Thanatos, the original ruler of Lux, alongside the current Grandmaster Endymion. He had escaped Ta’tarus, which was a barren underworld ruled by evil drow, but found the sunlight to be too intense. He cut his eyes so that he could exist on the surface. His sacrifice called a keyblade to his hand, and he was immediately taken in by Thanatos and shown how wield the Keyblade. Once he was deemed a master as well, he left for Ta’tarus again and liberated it from its oppressors. He was then revered as the lord of the underdark, and would only take apprentices who he deemed truly worthy. Leading to him taking Du’an as his apprentice because of his natural blindness.
