These articles all relate to the Autropa setting

The Autropa setting is a generic high fantasy world; its main purpose to provide a backdrop for demonstrations and examples for use on the Dirty History & Hobbies YouTube channel. This setting will also be used for the Titans Awake campaign, which will eventually be made available as a series of adventure modules; the setting, as well as all forthcoming supporting materials for it, will be published under Creative Commons licenses, with most being issued under the CC-BY license.

One of the key features of Autropa is that it uses Earth as the basis for its physical setting. You can watch a video about the correspondence between game world locations and places from our world. While the game world does closely correspond with Earth, of course with some differences due to being a realm where magic is widely-known to be a real thing, the setting is not an attempt to play out a particular period or specific history from Earth's timeline. There is plenty of expansion room for the world of Autropa; but, for now, the action primarily takes place in the geographic equivalent of west-central Europe.
