Tbos AU lore/worldbuilding concept: Hearts of the Gods (and some regen/resurrection stuff)
Back at it again with the second half of that post. And this one + the next are shorter! This time we’re talking lore based off the Heart of a Heretic item in-game because I have many thoughts about it. Yap below
CW: discussion of cannibalism + organs/gore/body horror (???)

The in-game item known as “Heart of a Heretic” is actually what every god’s Heart looks like, and it holds some special properties.
The only way to kill a god for good is to destroy their Heart, lest you run the risk of them eventually regenerating their body if they still have a source of Devotion/loyal followers who live on after their death. This is because the Heart is where a majority of a god’s divinity/divine power is stored, emanating from within it before spreading outwards to the rest of their body. Divinity and Devotion in ichor (godly blood) are what oxygen is in mortal blood, and the Heart pumps it through their body to sustain them.
This is also the actual reason why Narinder tells Butcher to take the Bishops’ Hearts after they defeat them.
Failing to destroy her Heart is part of the reason why Yngya’s whole situation played out as it did, as well.
As I’m writing this I’m beginning to think Narinder’s resurrection ritual also functions on some sort of reverse-engineered version of divine regeneration, where the flow of Devotion necessary to regenerate a body is flipped (transferred god-to-mortal rather than mortal-to-god), allowing the follower to regenerate their body with Devotion collected by the god instead.
Alongside harvesting Devotion, It’s also a relatively normal thing for gods to cannibalise other gods as another means to gain power.
If a god eats another god’s Heart—they absorb a part of that god’s power. This provides a boost in strength that would have taken way longer to achieve if it was to be done just by farming Devotion. It also has a similar satiating quality to harvesting/“eating” Devotion, but much stronger. Additionally, due to the high amount of divinity/Devotion the Heart holds—consuming it all at ones gives the god who eats it a momentary high that’s hard to replicate with anything else. Alongside the power it holds, this quality may also be the reason certain gods choose to seek out others’ Hearts.
If a mortal tries cannibalising a god, they are guaranteed to die immediately no matter what (and likely painfully too). Mortal bodies are not built for hosting divinity + the level of Devotion that a god’s body contains, so they will not be able to handle it.
A god’s body however can adapt to handle god-on-god cannibalism over time through physical mutations (mostly internal, but some visible on the outside as well).
The downside of god-on-god cannibalism is that if one overdoes it, their body can develop a dependency not only to Devotion itself (which is normal)—but to the actual flesh that hosts it as well. At that point, if they don’t eat godly flesh for long enough, they’ll begin to starve, and their body will attempt to feed off of its own divinity by eating itself from the inside as a last resort. This becomes a possibility thanks to the mutations/adaptations a god undergoes as their body adapts to god/god cannibalism, and is just as bad to experience as it sounds. It will also kill the god who goes through it if their hunger is not sated quickly.
Hearts are very hard to come by nowadays (most gods have already died and had theirs destroyed), so the only viable substitute to stop your body from attempting to eat itself alive if you find yourself in that situation is to eat Devotion-filled mortal flesh instead, which sates the hunger if consumed consistently.
It can also be satiated by consuming other parts of gods’ bodies, as well as god-tears (the ingame resource), but they, alongside mortal flesh, don’t provide a power boost like Hearts do, because they aren’t as saturated/rich in Devotion/divinity as a godly Heart is. Substitutes also don’t bring the same rush as eating a Heart would for that same reason.
These are my Horrors beyond comprehension I made to put Butcher and The Fox through, I hope you don’t like them at all /j
Btw, do not ask me why killing Marcy gives you a Heart of a Heretic in canon, I have no fucking clue💔 I’m retconning that part out of my AU because I don’t like it lol
The next and final part of this post is about Butcher and will be up same time tomorrow
