When I saw the Faztober prompt "the security guard", I read it in phone dude's voice, so I had to draw the security guard from FNAF 3. Well, my AUs version of her.

This is Theren.

The Fazbear's Fright horror attraction that she worked at was a covert effort to teach people about Fazbear Entertainment's dark past whilst gathering ghosts in order to help them reunite with their loved ones.

She didn't expect each night to become a fight for survival.

The Springtrap of this Fazbear's Fright was Vincent Taylor, her dad's old acquaintance. During the day, everything is fine, but during the night, something forces Vincent into the back seat of his own body and starts to hunt.

Theren has the keys to the building, so is the only thing between the unknown entity and the rest of the world.

At least she takes after her adoptive dad, so Freddy's typical survival comes second nature.
