Mairead raised an eyebrow at the new students and then laughed as she began looking for a way out. After a few moments of casually walking around the room, Mairead walked over to a wall directly underneath an air vent. Mairead noticed one of the first years making a giant pile of chairs with the obvious intention of rescuing more than himself and chuckled.

[i]"The bloody fool's bein' kind. That'll get beatn' out of him in a jiff."[/i] She muttered to herself as she lined up the auditorium floor with the air vent. She knelt down to the floor and placed her palm in the corner of the wall and the floor as a pale green glow lit up her fingertips. 

Mairead took a few deep breaths and focused, her green eyes turning almost black as a small crack appeared in the floor. The glow in Mairead's fingers got brighter and she stood up as a thick black vine with inch long thorns sprouted from the floor and snaked towards the air vent. A reddish glow came from Mairead's other hand and the thorns receded into the vine and the tip of the vine wrenched the grate from the air vent. She chuckled a little more and hoisted herself onto the vine, carefully willing it to stay strong. By the time she reached the air vent and crawled inside she was almost completely out of breath and quickly gave up control of the vine, causing it to wither and fall away from the wall. She took a moment to catch her breath before she began crawling away from the auditorium and trying to remember the map of the school well enough to navigate the vents.

After a few wrong turns Mairead found the hallway leading to the dorms and punched the grate off the vent, sliding down the wall and straightening her jacket once she stood up. She looked around for any other students and smirked as she began sauntering towards the dorms.
