GURPS: Church and State
From GURPSworld Wiki
Much more to come, basic intro:
The Barony of Rotbrueck (Red Bridge) lies in the southwest corner of the Kingdom of Valderland. Valderland struggles to maintain it's independence from the expansive (but declining) Holy Quadrangle Empire of Man to the south. Rotbrueck encompasses and protects a key pass through the Braunstein Mountains, called Fuessen Pass. The town of Rotbrueck lies at the convergence of two minor rivers, the Snow River and Greywater River, and is the only bridge over either. The Church of the Quadrant is shifting in influence from Esus, the Lady of Life, to Ampul, the Lord of Light. A vicious civil war lies 13 years in Valderland's past, and much of current politics is colored by the shift in the Church, or the redressing of grievances from the civil war.
Starting year: 1348 years since Burn's Crossing 3217 years from the founding of the Church of the Qaudrant (or the Church of the Four)
