Short-ish Adventure

I- um... I'm honestly not sure how I'm going to slide you into this story. Writing is a bit difficult. Quick question: would you rather read a choice-based story or write one? Ah, no matter. Let's just say that you wake up and find yourself in a big room. You can't see the ceiling, because it's like the roof extends infinitely. You notice that next to you is a man, sitting in a chair reading a book with no words. You ask him where you are. "I don't know either" he has absolutely no clue. You turn around, and behind you are two doors. A green one surrounded by vines and moss, and a red one that is...


...on fire.
