The house is emptied; Your daughter went to a mandatory practice session for the case a second _Visitation_ might occur. You grab some food from the fridge and make your way to the railway station of your town where you work as a train conductor. Since the first _Visitation_ happened about a century ago, trains form the main means of transportation through the vast emptiness between the few towns that are scattered across the land.
