The Wind Magician injected himself to disrupt the very process that he is supposed to judge. I'd look for a way to strip him of his powers and then beat the tar out of him; failing that, I'd look for a way to kill him.
Bit confused with the timeline now tbh. During the black council meeting they said ghat Lis would have 3 years to learn magic and then be evaluated. However apparently it's been 10 years since Noa was "murdered" and was healed by Luna? That doesn't seem to he correct
