Evienne and Russell
The bright flash of the Dark Mark was sudden and it was barely a moment later that the headmasters voice echoed throughout the castle. Springing up from her desk Evienne made her way out of her classroom and into the halls. Moving through the tower she herded the students into the Ravenclaw common room, the one closest to where the were.
It took a little bit but eventually she got a group of first year students calmed down and settled though they were still understandably scared. Hell she was an adult and she was worried, though she didn't show it. They managed to get on or near the grounds. She was sure though they wouldn't get into the castle. She had started to move along the common room, keeping watch over the students when she saw a familiar form.
