The Ten Stonehearts of the IPC - Lore and Potential (Star Rail Theory and Speculation)

Throughout our journeys in Star Rail, we have met a few of the IPC's Ten Stonehearts, elite members of the IPC who each possess a unique Cornerstone. In this video, I go over what we know about the Stonehearts, and what we could see from them in the future.

The thing about Aventurine cracking the cornerstone wasn't related to him being able to access its power, it was about fooling Sunday.

That also caused him to be able to access only a small amount of its power.

Just a few things of note:

Opal is confirmed to be a male through Aven's dialogue during the story.

There's also an IPC employee named Thea at the hills of creation on Belobog who states there are 11 directors, so Diamond + 10 stonehearts!

Gotta say, Welt just makes sense to be the Star Rail mascot for your channel. Great Video as always!

Definition of Cornerstone: an important quality or feature on which a particular thing depends or is based.

This puts a whole new meaning to Stonehearts, it isn’t referring to people who have a heart made of stone, but rather explains that their heart is their cornerstone.

The Aventurine Stone is also known as the Gambler Stone, it brings opportunity, and attracts prosperity. This gemstone being Kakavasha’s cornerstone makes a lot of sense.

Topaz stone calms a bad temper, it also improves mental clarity, focus and increases confidence. In Topaz’s demo (or trailer?), she’s teaching a whole class on how to collect debt. Topaz is full of confidence, confidence that even Aventurine doesn’t possess. Her cornerstone is a perfect fit.

We’ve heard of Opal, Obsidian, Jade, Pearl and Diamond. This amounts to a total of 7 of the 10 Stonehearts, I am including Diamond into the count because they would also depict themselves as a Stoneheart, as someone whose heart is a cornerstone.

The Diamond Gemstone absorbs and amplifies the thoughts of its user, as well as the strengths and weaknesses of other gems. The Diamond was also used as detoxification against poison, since it was said to protect against it. Most of these descriptions can automatically link Diamond to the creation of the Cornerstones, and this has lead me to believe that Cornerstones were originally Amber Stones fallen from Qlipoth’s very own body, until Diamond came and used the Path of Preservation to make them into something more. This is why all of the Stonehearts say “All for the Amber Lord”, because their heart, their cornerstone, although shaped by Diamond, originated from the Amber Lord.

I’ll look into the other Stonehearts we’ve been told about and leave a description of their gemstone in a reply under this comment, and then I’ll take a guess as to what the remaining 3 unknown Stonehearts could potentially be.

It's interesting to point out that among the known Stonehearts, Obsidian is the only who was not named after a gem, from what I know Obsidian is not considered a gem.

One thing I noticed that you didn't specify was that the emanator powers granted by the cornerstones originate from diamond himself. Essentially diamond shares his emanator powers with the other nine members of the stonehearts.

The 10 stonehearts truly are the most interesting people in hsr

I might be looking too much into it however in the Myriad Celestia trailer about the IPC theres a scene where a guy throws down some gems, theres only eight but a few look familiar. Theres Topaz, Diamond, and I believe the two of the three green ones are Aventurine and Jade, if this is a hint and not some random scene then the other stone hearts we might get are. Amethyst, possibly Emerald, and the blue one is either Zircon or Aquamarine.

It's been awhile since I've researched gemstones but these are my best guesses. (Also one of the gems might be obsidian but it's hard to tell because of how the light hits it)

I both love and hate the IPC, characters like Topaz and Aventurine are pretty lovable but the company as a whole is definitely corrupt. Not only do they ditch planets then demand debt repayment, but there's also a hint in Aventurine story that they might have also been the 'men in black' that sold him into slavery. So it's going to be interesting to see what kind of person Jade is.

Since Penacony was the IPC's before I do understand why they belive this planet is their's. Plus the fact it was a universe prison makes this planet the craziest to go for a relaxing break

[chuckwisss]

Yes finally a video about themm i have been waiting thank you

[BaraKingu]

Wouldve been great to guess their traits based on the stone they are referencing like adventurine and luck etc

[deathsinger]

I really like the stone hearts as antagonists, they are really interesting

[igricRBX]

Are they something like Fatui Harbingers and the stones are their Delusions or are they HSR's equivalent of Archon/Gnosis? (I'm still new to the game)

[therenegade]

I think obsidian might be the hacker that wolf mentions

[poke_lore]

I would like each stone to be a different path, with some repeat paths. I know diamond is going to be preservation.

[martingaming]

Cant wait for jade, i hope they dont ruin her like they did with acheron making me skip 2.1 🔥 she is so pretty love her hairstyle and hat💚

[marcusbullock]

I've been curious about these things

[Yaoyue春]

I want the speculation update about this🙏🏽

[xoaeri]

when did jade activate her cornerstone? i need to know this. and these theory’s are actually spot on and what i’ve been thinking about them as i love topaz and adventurine

[MaxOutGuy]

Im not sure but i think diamond isnt actually counted in the ten stonehearts and is just the leader of them. An ipc npc in belobog named Thea when you ask about topaz says that there are 11 directors in her department which i would assume means that diamond isnt counted among the ten and is just the leader. So this would mean that there are still 4 unknown stonehearts
