Mayhem in the Wizarding world

The train was boarding soon,Maeve Black ,Morgan Sivons and Chorus James Were all waiting in compartment number 3 for there friend Mars Riddle(she belongs to Slytherinquennbs). Maeve was sitting down whilst the other 2 were sitting together on the over on the other side of the compartment.Eventually Mars had arrived but she had brought a unnerving look with her she sat herself down onto the patchy leather sheets and shuffled closer And whispered into Maeve's ear.
"I talked to the cloaked woman,"Mars said, her voice cracking.Maeve's eyes widened in horror, thankfully no one noticed.Her body froze her eyes shut her unconscious body left there till she awoke at the end of the train ride If not for Mars's violent shaking.
Maeve grabbed her bag and her book and headed off the train with all the other 3rd years.Not surprisingly her friends Morgan and Chorus had disappeared. Maeve was unusually nervous. Her brother Regulus and his best friend Mattheo Riddle joked about her saying she was just paranoid.
As all the third years were sent to the great hall But what was strange was that they were asked not to bring their wands or any of their familiars biased she still slid her wand into cloak pocket as well as her friend Mars. They headed towards the hall with everyone else as she entered the hall the doors slammed shut Meaning mars would be locked outside and so would everybody else
