A couple years ago I took the Demon subdomain and created the Abyss domain to replace it. The process used might be useful for combining other domains, using a subdomain as a starting point. For instance, the Heroism subdomain (Glory domain) might be useful in bridging Glory and War, and the Defense subdomain (Protection domain) actually is a nice fit to the War domain, and could be used to bridge Protection and War (‘Guardian‘ seems like a good domain name here). Knowledge and War might merge by way of Tactics (which is already a subdomain of War).
The Season subdomain (Weather domain) is even more interesting to me, since it could be used to merge Weather with the elemental domains to get a domain for each season:
- Weather + Water = Winter
- Weather + Earth = Spring
- Weather + Fire = Summer
- Weather + Air = Autumn
There are many ways this could be done. It may prove interesting to explore them.
