Sarah Treveney

Sarah Treveney is Alex Treveney's older sister. Like Alex, she is also able to use magic. Sarah was the Night Keeper at the Nightschool until her disappearance.

Personality
She loves her younger sister Alex Treveney with a fiery passion and is working on getting her to go back to school. She has slowly been rising in popularity at the new school due to the opening of after school clubs and coming up with ideas such as sketching vampires so they can be put in the yearbook.

Despite being rather scatterbrained, Sarah is well versed in magic, which is how she taught Alex to control her Astral.

Powers and Abilities
Although Sarah is able to use magic, she isn't that good at it, as seen when her sealing spell fizzles. However, despite that, she seems to know a lot about magic and how to use it, as she is seen tutoring Alex on using her astral in a flashback.

Sarah's astral has yet to make an appearance.
