So I was thinking about what side quests or dungeons would make a good stand in for the missing Nine Divine quests for roleplay purposes. Three of them are already covered: Dibella, Kynareth and Mara, but what about the other six?
For example I was thinking that Forbidden Legend would make a good quest for Julianos, or if that is too much of a stretch there are a couple of forts containing shrines to him. Stringing them together could make for a nice little story.
The others may be harder. What would be your custom questline?
I would say that Forelhost or Skuldafn could be a stand-in for Akatosh (but I'm leaning more toward Forelhost). The mini-quest is called "Siege of the Dragon Cult," which fits Akatosh's avatar nicely. Forelhost is one of the more difficult dungeons in Skyrim proper, which suits Akatosh's position in the pantheon.
It's a stretch but Skuldafn might be a stand-in for Arkay. Skuldafn contains the portal to the afterlife in Sovngard; Arkay is the god of burials and funeral rites.
