For a few months now, I've had serious writer's block. I can't think of anything to write about at all, and I'm getting sick of it. I want to write a good fantasy epic, but I don't know where to begin or how much backstory to come up with before I begin. I also want to write a Metroid fic, but I just don't know where to start. I don't know how to get ideas or anything. Help me out.
