Builder Roads
From The DarkMod Wiki
The Builder Church is always continuing its mission to tame and civilize the land. Outside the city, new monastaries (more like small fortresses) are built to protect and cultivate the nearby resources.
They are the only places beyond sight of the city walls where a civilized man can feel safe, and they are therefore heavily used by merchants, mercenaries, and any others who cannot travel by ship. The roads between the larger and more prosperous monastaries are often paved with flagstones and patrolled by builder guards. Deeper in the wilds, travelers are grateful for a dirt path and a straw bed.
By collecting tithes from these travelers, the Builders gain a great deal of wealth to finance future building projects.
