What's accepted as fan fiction and what's not? I was intrigued when I read about the writing contest Blizzard is holding, as becoming a professional writer has been my goal since about six months ago. I love Blizzard games but I've never cared too much about the lore. So I started ploughing through the wiki for information about the Diablo Universe and I'm now about halfway through the first draft of my short. The "problem" is that I'm all about the small details. To make my story feel believable, I want to make as many references to universe and its customs, creatures and characters but I feel like there aren't enough information available about certain areas, creatures and characters. So I have a few questions here, the first one is to what extent can I make this stuff up? I assume making up minor characters is completely acceptable, but what about making up my own creatures, factions and cities and perhaps adding details to already existing characters? Am I free to make up pretty anything I want as long as it doesn't clash with the exisiting lore? Assume here that I want to submit my story to the contest. My second question is fairly simple - Are there any common mistakes that beginners tend to do when writing fan fiction? Finally, my third question is about the diablo universe itself. How long, approximately, would it take to travel from Caldeum to, let's say Kurast? I need to get a sense of how the scale of the world map of Sanctuary. Otherwise, I fear that I'll end up writing something weird where something that would take months to travel is done within a few days in my story. Thanks!
