A Vampire's Artifact

I pushed a dusty chest that was in the 'unfinished basement' of the house my mom and I just moved in. To my surprise a drawing was underneath. It was a circle with three triangles inside.
Each triangle had an angel holding a cross. The weirdest thing of all was the fact that the red drawing smelled like fresh blood.

I didn't think twice and I erased it with a broom until it was nothing left to see.

Little did I know that a vampire named Nathan Jones was trapped underneath the drawing and thanks to me he was free to kill again!
