Son of a Preacher Man: Post-Apocalypse Edition

I has been three months since the World as you knew it ended. What was soon called rifts opened up all over the globe, spewing otherworldly monsters and odd miasma everywhere. Police and militaries were overwhelmed by the sudden phenomena and nobody was prepared: nobody except the tiny rural community around the mysterious apocalyptic preacher Jeremiah. By choice or through circumstance you've found yourself in this community. A scenario influenced by Dragon Age Inquisition, Dusty Springfield, High School of the Dead and literally Jesus Christ. Also, there is no pre-apocalypse edition.
