With shame and disgrace, White accepted the new job.
All due to Green, he was removed from the mages hierarchy. Worst case scenario, Green never got assessed to see if he truly deserved the spot but, for some strange reason, White felt no animosity towards Green or the King.
Green deserve to make whatever choice he wishes, after all, Green is among the reason of their survival and existence. He protected the humans when they were nothing and never asked for anything in return.
Despite being disowned from the mages hierarchy, he did not stop trying to become a powerful mage. He hoped that one day, be would be able to retain his spot or get accepted once more.
