The Cult of Mirror Lake

You are moving into Mirror Lake, an isolated mountain town in the Blue Ridge mountains, to escape from some baggage you've accumulated over the prior years. You plan to work as a park ranger for a year or so, to recenter before continuing with normal life. While living in the town, you notice odd circumstances which seem to occur at an ever-increasing tempo. Then, someone you've grown to love since moving in disappears, and you race to find and save her from a local, darkly supernatural cult before it is too late. Luckily, you have made some good friends since moving in, and they are happy to help you in your battle against the present darkness. Who will live, and who will die? That is up to the decisions you make. Anyone can perish in this scenario if you act suboptimally.
