The Absolute is female as per a few of her disciples.
The Cult hangs out in a Selûne's temple and there is a note/book early in the zone that mention the Selûnites in the area went weird a few years ago (pre-Absolute as all the monsters attacking is recent according to the Grove Druids).
The Cult leaders are planning raids on certain sections of the map. Drows seems to have other plans than the goblins (they kidnapped the Duke, the goblins just wanted to pillage Waukeen's Rest).
The Cult do business with the Zhentarim (Bane followers) and "hired" a priest of Loviatar (the Maiden of Pain is a servant of Bane) without trying to convert them. But they really want to kill the druids and tieflings for some reasons.
Dark Justicars, a Shar order, came over the area a while back and disappeared into the Underdark. The leader created a shadow fog that encircle the Moonrise tower and kills anyone trying to go there. The Cult has a way to pass through that fog and the Moonrise tower is their HQ it seems.
The Selûne Temple Underdark section has a Sharran gem at the top of statue (thematically super weird).
Netherese magic could mean some Shadovars are involved. More Shar followers unless they switched allegiance.
The Maglubiyet goblin priest who is prisoner in the temple mention that the Absolute is gaining followers by offering them whatever they want. He doesn't think it's a real god.
The Githyanki who attacked the ship were actually after Shadowheart...more precisely, the artifact she is carrying. Her pod in the ship was different then the others as well. It could be linked together. So not a 1 vs 1 thing, but multiple group/gods acting against each others.
The Moonrise tower is mentioned in a document in the Harper's cache. Could be a (former) Harper base.
