Haro might have taken over Shamura's domain as a god of knowledge when Shamura's skull was split, and they lost their mind when the One Who Wants/Narinder was banished, as they were no longer able to act in their capacity as master of that domain.
As Haro themselves may no longer have any worshippers, (and their worshippers might have lived now in the camps where Haro is found), their own powers dwindled, explaining why their crown is crossed/dormant. It may not be dissimilar to how the Lamb's red crown is crossed when in the presence of the bishops.
- Alternatively, it will be a Final Boss for a secret ending route, where the Lamb realizes all the horror and atrocities they have been forced to do have helped release something worse than the Four Bishops' rule ever was.
- The Lamb will kill The One Who Waits and become the new god of the land.
- Confirmed. The Lamb will have a choice on whether or not to become a final sacrifice and if not, the final battle begins. After the fight, the Lamb pretty much usurps the One who Waits as the new god of the land and can choose to kill him or simply turn him into one of their followers.
- Jossed. The One Who Waits only intends to sacrifice the Lamb to revive himself and use the rest of the cultists for mysterious purposes, likely nothing good.
- Alternatively, this will be the end-goal - a mass-suicide powered ritual to free The One Who Waits.
- Jossed. The One Who Waits is only interested in sacrificing the Lamb.
- In addition to this, the Lamb is perfectly capable of guiding wayward followers back gently rather than sacrificing or publicly torturing them.
- Confirmed. The One Who Waits was a part of the Four Bishops, with his old name being Narinder.
- A post-game campaign featuring new levels and challenges.
- A secret sixth bishop comes out of the shadows and becomes the boss for a new stage/biome.
- A brand new island for your cult to conquer complete with its own set of stages and bosses. You travel to this new location via ship or boat. Most likely Plimbo will give you a lift there.
- A new questline given to you by The One Who Waits if you recruit him as a follower, expanding upon the origins of the Old Faith and how he and his siblings came into power and the subsequent fallout leading to his imprisonment. Specifically their pre-crown bearer days.
- Expanded character customization features like head accessories such as hats, masks, etc. and customizable clothing for your followers.
- New building options for your base both functional and cosmetic.
- A family / generational / inheritance system where you and your followers can now have children / descendants.
- Not in Relics of the Old Faith
- Sins of the Flesh allows your followers to breed, mostly to inherit traits.
What if the Bishops are, in truth, merely ascended mortals, like the Lamb? Meanwhile the true power, the actual deities, are the crowns? Perhaps they are all that remains of the gods of old, mere symbiotes, using mortal hosts in order to ensure their survival in an age of constant deicide. Even if their mortal hosts die, the crowns survive, get claimed by another, and continue as if nothing happens, because they do not truly need to be the objects of worship, merely drink up the devotion towards another.
- Unlikely. If anything, it's likely that the more dignified statues are the gods of the old faith, before the betrayal of the one who waits. After the betrayal, they're gravely injured, and their power appears to have similarly diminished. Shamura, for example, was mentioned to have been the brightest before their skull was split.
The crowns are more likely symbols/extensions of their power, or tools that let them use that power more effectively, rather than being the source of them. We see Shamura without their bandages, and it reveals that the crown is physically rooted into their brain, likely preserving their life, and keeping what's left of their mind together after the damage they sustained, but with the result being their madness. After the betrayal of the One Who Waits/The Heretic, and to deal with the threat posed by the lamb, they may be more likely to draw upon the powers of their crown.
It's also notable that you don't take their crown, you take their still-beating hearts instead, which suggests that the beings themselves have power, something supported when you battle Narinder/The One Who Waits, who is still able to fight you, and draw on a One-Winged Angel form similar to the monstrous forms of the other deities of the old faith, despite giving his crown to the lamb. - Seems at least partially confirmed in the "Relics of the Old Faith", with Leshy and Shamura stating they found their crowns, and all of them having dealt with ???
- An epilogue cutscene may extend the 'origin story' aspect by showing the point of view of the Lamb looking down at His chosen people, seeing them worshiping a golden calf and, perhaps after having a brief visible flashback, beginning to write some new rules. First among them: 'thou shalt have no other gods before me.' Never again.
- Bonus points for a character in the DLC being an anthropomorphic bull.
- This does not happen.
Alternatively, more humorously/horribly (depending on your perspective), the brain damage caused by The One Who Waits may have caused Shamura to forget their own gender
- But their siblings would still remember their gender and address them by their old pronouns. It's not that deep.
- Also, if they ARE plural, they would be pangender and thus, non-binary.
The Bishops will somehow be resurrected and try to take back the Crowns but will be caught by the Lamb who decides to spare them and force them to help build up the Cult. They will then set up camp in different locations around the Cult of the Lamb's local area and can be called on to aid in a Crusade with each Bishop having different powers based on what their Crown represented.
- Confirmed, you bring them back in the Relics of the Old Faith and they become followers just like Narinder
- Well, he looks more like a fox than the confirmed wolf characters, and foxes are traditionally known for shady deals. It is possible that the character was originally going to be a wolf, but was changed as a reference to another shady fox dealmaker called Red(d), though.
- If they have a feminine voice:
- Stephanie Varen (Since she already voiced a cute divine animal.)
A separate lore piece can be found as a letter called Offering to the Owl in which a hunting party asks that their hunt be granted success because of an offering left for them.
All of these separately give us clues as to who or what the First Gods were or looked like.
