Svigia
This fantasy world is somewhat inspired by the real world (and Warhammer fantasy references exist as well), but I have to say that it is my first world and am kind of proud of it. It is (technologically) set in the middle of the 18th century with a focus on the combination of magic and technology (although I (so far) barely wrote any articles about it).
The themes reflect that by focusing on a magical industrialisation while exploring conflicts that arise with less advanced civilisations and the hubris of technological superiority. That does definitely not mean that one side is exclusively in the right and the others are the bad guys (my player totally agree on that), but the stories have a rather neutral tone with individual people coming to their own conclusions.
Additionally, one should be aware that all the articles are written in German.
