I think the gemstones could be the karma core, who else better to teach humans about them than an actual enchainer.

Actually in some culture, like Celtic... Deer were viewed as sacred messengers from the Otherworld who could lead travelers safely through dense, unfamiliar forests and spiritual realms.
So Joyous being represented as a deer is on point.

9:42 I think Sunbringer never eradicated the Hollow. Roscaelifer IS the Hive Lord Hollow. Since she is its Enchainer, she was likely able to convert it into a liveable space. That could also be why Singularity Leakages are even a thing.

"No one knew the price of prophecy"

My intepretation of the Sick Star is that it's the Hive Lord Hollow itself. We see in the Prophecy MV that Sunbringer holds an orb with the same sigil that shows up in Lindverne's eyes (Hive Lord Hollow sigil) which I see as a potentially sealed or compressed version of the Hive Lord Hollow. This makes sense because:
- The Sick Star is the Beacon of the Lighthouse (Roscaelifer)
- Scamall Hollow is a Companion Hollow with no accompanying Great Hollow (Hive Lord Hollow still exists, which allows Scamall Hollow to exist)
- Scamall Hollow is supposedly the power source of Roscaelifer, but it makes more sense that the Hive Lord Hollow is the true power source considering how intensive Rosetta Data computation is
- TOPS/HAC seems to be looking for something inside Roscaelifer, my guess is that their true goal is the Hive Lord Hollow itself, with the secondary goal of capturing/retrieving all of the split Sunbringer Karma Cores

As for the Sickness the Star is suffering from, it's kinda hard to guess with the limited knowledge we have at the moment, but my personal guess is that the Great Hollows cannot function without an Enchainer and will slowly dissipate. Sunbringer might have killed the original Enchainer which caused the sickness.

The Porcelloy Spine is also super important, my belief is that they are going to use Anby's blood to create the perfect Vessel (Silver Soldier project might have been an attempt at cloning Sunbringer) to hold the Sunbringer's Karma Core, then using the implanted Porcelloy Spine to control the Vessel. Maybe even mix in the Exaltists' Sacrifice Technology in there somehow.

Sick star is definitely whatever is enabling the Rosetta data creation.

If you stick around Flint workshop in the new location, there's some interesting dialogue on how CCD, which shiuld only be calculating the data, consumes large amounts of porcelloy with no public knowledge of this going on or its reasons.

The Antlers in my opinion is connected to Joyous because according to Celtic or Norse lore, it represents the path way between the earth and heaven, in this case the Hollow where the Creator, aka god resides. Joyous beings the one that pioneers in Hollow Exploration is the connection. And the reason why I choose Celtic and Norse version is rather simple, Roscalifer is based on England.

Finally, someone made a video about Bangboo Prince. Can't wait for more lore reveals.

9:01 ngl this gives me so much Hollows from Bleach Vibe cuz it follows the same rule that a stronger Hollow that consumes many of his kind can potentially become Sentient

Enchainer Larva= Gillian/Adjuchas
Enchainer= Vasto Lorde/Espada

Col Vike that has her Karma Core corrupted would be the equivalent of a "Hollowfication" and Remielle that has control over it is a "Vizard"

I think the Star is actually the Hivelord Hollow itself, the Prophecy music video hints at it honestly. Sunbringer left the Hollow as a Larvae and later came back to take the Karma Core for herself, collapsed the hollows ether to a minimum and is hiding it somewhere in her Clocktower. The reason i think the Hivelord Hollow still exists is mainly because of the Sandbox around Roscalifer! Roscalifer IS the Hivelord Hollow itself in a sense, this is also why that storm under it exists, it is essentially a leak of ether from the Hivelord Hollow (Singularity Leakage) and the reason Eldreda needs so much Porcelloy is because it must have become unstable in reacent time, so now she is trying to find a way to contain the hollow and keep it from fully reforming itself. Sunbringer being a Enchainer also fully confirms my theory that the Night Horror is an Enchainer, since it also is said it could leave the hollow

The Falling Star is Phoenix. There's an extremely strong visual at the end of current patch where a falling star crashes near Lindverne, Phaethon and Remielle, which turned out to be Phoenix. She also had a safe with her~
Aside from that, very great observations. I came to the same conclusion but I didn't know about the bangboo story. Very interesting!

Tbh I like the theory but I'm still firm believer of the creator being the evil king since even divine figure can be called king such as Zeus being king of the gods and most Abrahamic religion called God sometime called  king of king and it's clear that sunbringer somewhat of a parallel to the devil and the devil used to be an angel or in this case an emissary of the creator which what angle originally meant mesangger and emissary and angels never use the term king but rather prince such as the rank of principalities and archangel Michael being refer to as the great prince so sunbringer is the prince and the creator can be the evil king for my reasoning

Complete shot in the dark but based on her generally sickly portrayal and the ending scene of 3.2 I have a gut feeling that the sick star is Pheonix.

I think Roscaelifer is the Hive Lord Hollow. Since Sunbringer is the enchainer of Hive Lord, she is able to bend the rules of the Hollow, and we see Singularity Leakages happen inside Roscaelifer. I think this implies that Roscaelifer has properties of the Hive Lord Hollow and might be the Hollow itself transformed into the "Lighthouse" by Sunbringer. (And so, the tower that ha once stood cold and imposing finally began to shine with a warm light.) But the last page tells of the "Lighthouse" going dark, implying that Roscaelifer could go back to its previous state, being the Hive Lord Hollow and The Creator taking it back.

My theory is the sick star is Phaethon. Since it's sick it needs to be cured. In the story phaethon need a treatment to "cure" them and can fully control pyrois power

6:57 About the Antlers in the Bangboo Prince Story, because i assumed that it could be none other than Joyous, i searched what hidden meaning antlers can represent, and one search result was that the can symbolize "carving out a new path", or "rebirth" which, if true, could reference his invention of the Carrot, as that served humanity to carve out the new path (navigate) the Hollows🤔. But i'm not an expert on the matter and the internet can also be wrong at times so take this with a grain of salt 😁👍🏻

we are getting another "possessed by creator" fight at the end of 3.4 arent we

It's not just a "star", it's a "sick star"!

Crackpot theory. TOPS is gonna turn a Void Hunter into an enchaniner, or, what I feel is more likely, revive an anctient enchainer through a Void Hunters body. I think they plan on using Sunbringer, but for some reason Im getting a lot of red flags on Ramielle rn and think she might do a self sacrifice play to save her old friend.

i think the sick star IS the hive lord hollow.

rosetta data is supposidly the CCD calculating hollow activity and possibilities.

what better way to simulate a hollow, than using a hollow.

it would explain why databoo get a vision of sunbringer, if she is the enchainer of that hollow, she is part of it.
