In my experience, some players will be clerics, druids, or rangers that advocate that nature should reclaim lands or that civilization should be stopped. I want to play a cleric that believes that civilization should spread as much as it possibly can because chaotic places should be brought to order.
I’m partially inspired by Abadar from Pathfinder’s Golarion. He wants to bring civilization out into the wilderness and tells his followers to civilize frontiers. That concept is really cool to me, and that’s what I want my character’s motivation for becoming an adventurer to be: a holy mandate to expand civilization.
I looked at the deities on the civilization domain page of the wiki, but none of them explicitly said they want followers to civilize frontiers, from what I saw. Most seemed to see civilization as a useful means to an end, rather than a worthy goal on its own. The best I saw from that page was Amaunator, due to his love of order, but the wiki also seems to suggest that Amaunator is dead.
If it helps, I’m playing a lawful neutral Dwarf and not concerned with the race of the deity. Furthermore, I’m unconcerned with the domains available.
