A homebrew campaign has two crucial components: the world and the story. At this point in the series, we’ve already built a beautiful, vibrant, living world that is populated with unique characters and filled with civilizations and stories waiting to be encountered. We’ve written one arc, the first arc of the campaign, and I’ve talked about one-shots. Now, however, it’s time to look at the most critical part of the story: the central arc, or the arc that covers the entirety of the campaign. Sure, there will be other stories and some detours along the way, but this is the trunk of the tree from which all of the branches extend. In fact, that’s how I want you to think of this session: we’re building the trunk of the tree.
