At least one depiction on the ceiling, and at least one aspect with its own idol somewhere in the complex, and possibly something like a crow sitting on the shoulder of the central idol.
Hmm, the former was a role that wound up with Nut and Nyx, background deity of the night sky. Important and present often, but not often worshipped as such.
The latter is a bit of an Odin's Raven/Athena's owl thing, though anyone imitating it in reality would have to cope with poop stains on their clothes.
All the shamans have been trying to figure out what acts of Crow actually mean and what actually are acts of Crow. The problem with orange and blue morality is what actually counts as good for you in their world view can be near nonsensical in your own. So Crow can be both alien and trying to help... what classifies as 'help' is literally the job of some shamans.
Problem is that Urban centers have different views on what is most important. The nomad Hunter Marches rank military far more high on the list than other sections of The People. Adding in the proto-guilds is going to force a god of craftmanship to spawn. So while agriculture is the very much important as you move more people out of the farming jobs priorities of important shift to echo their own lives.
So while agriculture ends up in the 'duh' pile of important things its not really first on the important things list for everybody.
Well, considering our holy sites, they'd influence how we view each deity:
Sacred Forest
-Crow the Teacher, the cosmic mystery hiddden within the leaves. Remember Sacred Forest is where the Blackbirds are trained.
-Gwy and Gyo, the All-Father and All-Mother as the parents of everything that lives.
-Fythhagyna, the Harvest god, bringer of the land's bounty. Likely to warp to become an overall nature deity.
-Mathulmyn, likely to follow the facet most like Bynwyn of Sacred Forest, the elderly dispenser of wisdom to chiefs.
Valleyhome
-Crow the Watcher/Advisor, the one who spies upon the people and tells the chiefs. Remember Valleyhome is where the Blackbirds are used as heavy surveillance tools for crime suppression.
-Gwy and Gyo, the Divine Ancestors of the ancient families.
-Fythhagyna, the Wealth god, the source of all wealth and power. Likely to warp to become a prosperity god.
-Mathulmyn, likely to follow the facet most like Magwyna of Valleyhome, the wise knowing King who knows how to make everyone do as she planned. The depiction is very much keikaku-face.
Rainbow Trail
-Crow the Devourer, the one who consumes the dead. For obvious reasons as our necropolis.
-Gwy and Gyo, the Divine Ancestors of the ancient families.
-Fythhagyna, the Harvest God. Cue harvest metaphors and syncreticism with the Spirit of Death harvesting the souls of the dead.
-Mathulmyn, likely to be a blend/multiaspect approach as a combined ancestor spirit of kings, which pass upon death to dwell within their successors. All of them are buried here, you may recall, and their deeds are scribed onto the very walls.
Holy Sea
-Crow the Wanderer/Storm Crow(Syncretized with the rainbow storm pony of the nomads)?
-Gwy and Gyo, the Divine Ancestors of the ancient families
-Fythhagyna, the Bounty God. Here, where food comes from land and sea alike, she'd be associated with both forms of harvest
-Mathulmyn, most likely to be associated with Twythulmyn of Redshore, the King who knows the value of connections between the People and outside the People.
