Lith went to the Headmaster's office and because of the queue, he had to wait quite a bit. He couldn't say it was an emergency. Lith knew there was a traitor if not more than one inside the academy, so he couldn't afford to alert them.
When his turn finally arrived, the first thing he did was to close the door behind himself and ask Linjos to activate all of his office protections. Only when the arrays in the room started to hum, their magic so densely packed to be visible to the naked eye, Lith told him about what he had discovered.
"Anti mana toxins at the Lightning Griffon? This is indeed a serious matter." Linjos was about to use his communication amulet, but Lith stopped him.
"Not only there. They are also here at the White Griffon." His words made Linjos turn pale.
"We had no such cases here. Our average of promoted students is better than the previous years…"
"Yet the grades are dropping, remember?" Lith cut him short.
