The Vampire Oracle

The Oracle Academy is up in flames.
During a night of making cookies for a higher-ranked Oracle, I am faced with my only friend exploding at the gates, letting in vampires. Flooding the academy, they are only looking for one person.
Spectre.
Will he reveal himself just to save the students of the academy? Or will he stay hidden like he needs to complete his mission?
Adding fuel to this fire, I find out that there’s an enemy among the mix of Oracles: a vampire pretending to be one of us.
