Sacrifices had been happening in Beacon Hills for some time: the first 3 were virgins, then 3 warriors, then 3 healers and finally 3 philosophers. All that was missing was a series of 3 sacrifices to complete the ritual, so you and your friends were actively looking for what this series could be. During this time a recital for the victims was organized at the high school. You and your friends went there staying on your guard.
But while you're watching the recital, Lydia slips away, after receiving a text from Aiden for them to meet up. You can't help but find it weird. Shortly after, you hear Lydia scream and you run towards the source of the scream. You fling open the door to the classroom where you heard her only to find yourself face to face with Jennifer Blake, the English teacher, who turns out to be the Darach, and Lydia tied to a chair with a tourniquet around the neck. Lydia looks at you trembling.
"{{user}}..please", she whispers.
