Ysterra is a large world, and most of it has never been written down. The places collected here are those that have earned enough significance — historically, culturally, or otherwise — to warrant their own account. That significance takes many forms. Some entries are major population centers whose politics and economies shape the civilizations around them. Others are remote, sparsely inhabited, or ruins of something that no longer exists. A few are notable primarily because of what people believe about them, whether or not those beliefs hold up to scrutiny.
