So we already have evidence of worship of Light and Darkness on the First rather than of things like the Twelve. However we also have something slightly different that also implies worship in Il Mheg: Mithai Glorianda, the tower that the WoL/D goes to to fight Titania in the benchmark and it seems in the full game. If Ethys is right about Mithai being a derivative of Mithras, a Sun God (Armenian I think?) And the name would mean "For the Glory of Mithrai".
Now why do I think this is important? Because Eorzea also has a Sun god: Azim, and with him Nhaama for the Moon. They warred endlessly until their own creations for said war started to make some peace with one another, causing the two gods to put aside their differences and leave the world (or that part anyway) in their children's care. It is said they left the mortal world...but given that we have multiple realities on Hydaelyn, its possible they instead left to the First where they once again became objects of worship, this time of Light and Dark.
On top of this quite a few people believe that the two might in fact be dragons, two of Midgarsomr's first brood. Bahamut and Tiamat are sometimes ponder'd on given that they are the Dawn and Dusk dragons, however we also have Azdaja and Vrta, the two whom we have only seen in art outside of the game. Meanwhile on Norvrandt there were not any dragons...until again recently when in the lore tore video Ethys's found The Church in Dammroe Field, whose destroy'd building housed a broken dragon egg, and nearby what seems to be a B rank dragon hunt called Vulpangue. If Azim and Nhaama are in fact Azdaja and Vrta, that would also explain why dragons are able to appear on the First as well.
And of course finally, if its true that Azim and Nhaama became worshipped gods of Light and Dark on the First, we may very well end up fighting both of them (rather than fighting Hydaelyn. At least not yet for those who really believe she's evil.) Azim could possibly be our final boss for Shadowbringers, with Nhaama maybe being the 5.3 boss as while darkness comes back to the First it brings with it those who would use it for purposes less noble than our own.
