I wanted to create a list of domains for part of the Monster Overhaul.
Creating a list of 100 domains is easy. Creating a really good list is harder. Duplicate ideas need to be ruthlessly pruned. Idea that seem good on paper, but which nobody actually invoked for anything, need to be cut as well. The list grew and shrank for a few weeks, but I think I'm finally happy with it.
Greater Domains are areas that most pantheons place in a position of importance. They're the gods most people know (aside from regional deities and profession-specific intercessors).
"Travel" is the weakest inclusion on the list. I'd gladly swap it for a Fate/Destiny/Chance aspect, but Travel seems more crucial to D&D-type games.
It's tempting to roll The Harvest in with either Fertility or Livestock, or some other combination of the three concepts, but I think that's just because the association is so common in classical polytheism.
I've tried to stick to domains that have some historical precedent (i.e. at some point, somewhere, as far as we can tell, people invoked a god / patron saint / spirit of X).
Horses and Bears should be on the list, but they seem tied to a particular kind of setting. I'm willing to imply the existence of seas and deserts in a table (after all, they don't have to be local seas or deserts), but springing the existence of horses and/or bears on a GM might be impolite.
Serpents and Bees are two notable inclusions that sort-of imply a setting. Serpents are such a common feature in mythology (and snakebites are a constant concern), that I felt not including it would cause more problems than it would solve. Bees and beekeeping tend to fade into the background of most games; I'm not sure many GMs would be shocked to find that their setting included bees (of some description. Arnold's bees are probably horrifying).
The seasons should also be on the list, but since there are Season-themed chapters in the book, I felt it would be a duplication of effort to include a powerful semi-divine seasonal creature here as well.
After revising a shortlist a few times, I remembered this post from Daniel Sell (216 domains, with powers). It looks like we went down similar research lines, but I'm including it for the sake of thoroughness, and because I referenced it while drafting the final list. I also referenced Petty Gods (post here) and this post.
Are there any duplicate concepts on the list? Entries that could be combined?
Are there any obvious concepts that are missing?
And yes, there will be a d10 (at least) list of Very Minor Domains, to include Hats, Hindsight, Cowardice, Puppetry, etc.
