The Firewatcher {Gravity Falls crossover}

(FireWatch & GravityFalls crossover)

Dipper Pines needed an escape. He was trapped in a tragedy over his head after the loss of a life time. He took up the job in a remote, far off town by the name of Gravity Falls, a eternity away from his problems. His job is simple. Watch out for fires.

He's alone. Or he thought he was going to be. There's his supervisor and fellow watchman. The mysterious voice through a radio. A far off man in a far off tower sits and watches and waits. Everyone has a reason for coming to Gravity Falls. What's his?

Not really BillDip, hinted if you squint, but more friend-shipping.
