Archangel Michael arrived at Yancy Academy for his first day, his bright and flowing blond hair along with his imposing figure caused heads to turn as he made his way through the campus. Micheal strolled through the building in his disguise as a Religion Teacher since he was well versed in the subject. He checked each and every classroom in the building until he felt something familiar the mist being twisted to hide something. Someone or more likely something was trying to do the same as him hide their true nature as to not scare the mortals. Using Hecate's' power to hide was an admirable feat but Micheal could easily see through their facade as Hecate's power as a mere speck compared to the Archangels strength granted to him by God.
Micheal arrived at the sources of the anomaly the one of them was the Pre-algebra classroom where he saw one of the Furies showing just how important this demigod was. The other source of the mist was the Latin classroom where he saw a Satyr and Chiron himself. Chiron felt his disguise being seen through and looked around until he locked eyes with Micheal. They both just stared at each other for a good while until a young man with dark hair raised his hand and Chirons attention went elsewhere. Now knowing what was in here with him Micheal went back to his classroom and waited for religion class to start.
Chiron POV:
Heaven is watching us. They have not sent an Archangel to look after Greek demigods since the first one born by Zeus they didn't even intervene during WW2. Their metaphysical leader's omnipotence is coming in handy as it knows something we that we clearly don't. This is only confirming my suspicions that Percy Jackson is very important and should be protected.
