Takius

The third character to be introduced to the series, Takius, is a mage who wears a blindfold (a Dark Blinder) and searches the world for the ultimate truth. Her mission for this "ultimate truth" was put on her by her teacher, Zephyr (who also gave her the blinder). With the blinder and her original staff intact, Zephyr had the ability to control her. After going mad and being recruited by Dark Lord, he uses this ability to manipulate Takius in favor of Dark Lord's plans. Eventually, Takius is able to conquer her internal struggles, breaking free from her ties with him and removing the blinker permanently. To further this transformation she became a Sage, resulting in one final confrontation with the one man she ever loved. During the final battle with Zephyr, her master was betrayed by the Dark Lord, who had been using Zephyr from the beginning. As a result, he falls from a collapsing wall, only to be saved just in time by Takius; however, the two are killed from a spell Zephyr had casted previously; however, this wouldn't be Takius's last appearance in the anime. The voice of Takius would come to Roan during the final battle, encouraging Roan to fight on for he had lost all hope (some believe that Takius has survived the Lord of Vermillion spell Zephyr summoned). Takius's staff would then come crashing down from the air, canceling the attack Dark Lord had intended on using (somehow, the wand seems to contain the magic called Spellbreaker, which is the reason of the canceling effect). Maya carries out her wand as a memory of her. Her real name is Catherine, but hates being called that for unknown reasons.
