Helvéczia
This is an unofficial, third-party implementation of the excellent Helvéczia core rules, copyright Gabor Lux, 2021, and with his kind permission.
You need to get the Helvéczia rules in order to play. You will also find a wealth of inspiration for your games in the rules (and especially the excellent box set), too.
