Myriad Celestia Trailer “Deep Waters”: IPC Secrets, Stonehearts and Voice Cast in Honkai: Star Rail
The Myriad Celestia Trailer: “Deep Waters” explores a dangerous side of the IPC, bringing Jade, Obsidian, Opal, Aventurine, and several other familiar characters into the same tense narrative. Released on September 6, 2026, the trailer centers on promotions, hidden threats, secret orders, and the uneasy relationship between lies and truth.
The trailer also places Aventurine • Waveflair in the spotlight during the period surrounding Honkai: Star Rail Version 4.5. His limited 5-Star character event, “Over the Gilded Tides,” runs from September 12 to September 28, 2026, alongside the Light Cone event featuring “Summer Rides the Surf.”
What Is the “Deep Waters” Trailer About?
The “Deep Waters” trailer focuses on the hidden risks inside the IPC rather than presenting a straightforward character showcase. Its central setup includes a promotion with extremely high stakes, a banquet where conversations carry implied threats, and a secret directive designed to destroy itself after being heard.
The trailer’s central question is simple: what happens when everyone has something to hide? The official description specifically connects the story to the IPC’s dangerous internal world and the “Stoneheart’s Oath Ring.” This makes the Stonehearts and their relationships central to the trailer’s atmosphere.
Rather than explaining every mystery directly, “Deep Waters” uses short scenes and character interactions to establish uncertainty. The trailer leaves viewers wondering who is manipulating whom and whether revealing the truth is safer than maintaining a lie.
Why the IPC Matters in “Deep Waters”
The IPC provides the setting for the trailer’s conflict because the organization is closely tied to power, contracts, money, and strategic interests in the Honkai: Star Rail universe. The trailer's wording suggests its characters are dealing with more than an ordinary corporate gathering.
The mention of the Stoneheart’s Oath Ring adds another layer because the trailer specifically frames even this symbol of the Stonehearts as being caught in the surrounding turmoil. It does not, however, provide a complete explanation of the ring’s significance in the trailer description alone.
Which Honkai: Star Rail Characters Appear?
The trailer features nine named characters in its English voice cast, including Jade, Obsidian, Opal, Aventurine, Boothill, Himeko, Feixiao, Argenti, and Dr. Ratio. The official trailer credits all nine English voice actors.
| Character | Role in the Trailer Context | English Voice Actor |
|---|---|---|
| Jade | Stoneheart and key IPC figure | Faye Mata |
| Obsidian | Featured Stoneheart character | Erin Yvette |
| Opal | Featured IPC/Stoneheart character | Paul Castro Jr. |
| Aventurine | Stoneheart connected to the trailer's IPC storyline | Camden Sutkowski |
| Boothill | Returning character appearing in the cast | Andrew Russell |
| Himeko | Returning Astral Express character | Cia Court |
| Feixiao | Returning Xianzhou character | Anairis Quinones |
| Argenti | Returning character | Talon Warburton |
| Dr. Ratio | Returning character | Jordan Paul Haro |
The biggest draw is Obsidian, whose appearance gives the trailer another connection to the Stonehearts. The official English credits confirm Erin Yvette as Obsidian’s voice actor.
Jade also receives a prominent place in the cast, with Faye Mata returning as her English voice. Camden Sutkowski voices Aventurine in this trailer, while the remaining cast brings together characters from several parts of the game’s existing story.
Jade, Obsidian and Opal: Why These Names Matter
Jade, Obsidian, and Opal are particularly important because all three names are presented together in the official English voice credits for “Deep Waters.” Their inclusion reinforces the trailer’s connection to the IPC and the Stonehearts.
The trailer does not provide a complete character biography for each figure. Instead, their presence works as part of a larger mystery. This approach keeps the focus on the situation unfolding around the Stonehearts rather than turning the video into a conventional character introduction.
Jade
Jade is voiced by Faye Mata, who is listed first among the English voice credits. Her presence connects “Deep Waters” to the established Stoneheart storyline and gives the trailer a familiar anchor within the IPC setting.
Obsidian
Obsidian is voiced by Erin Yvette, making this trailer an important official showcase for the character’s English voice. The trailer’s emphasis on the Stonehearts makes Obsidian’s appearance especially relevant to viewers following IPC-related story developments.
Opal
Paul Castro Jr. voices Opal, and the character appears alongside Jade and Obsidian in the official cast list. His inclusion further expands the group of Stoneheart-related figures associated with the trailer.
How Does Aventurine Connect to the Trailer?
Aventurine connects “Deep Waters” to the wider Version 4.5 storyline, where Aventurine • Waveflair is the featured limited 5-Star Quantum character on the Elation Path. Version 4.5 Phase II places his Character Event Warp, “Over the Gilded Tides,” from September 12 to September 28, 2026.
His appearance is also notable because the trailer arrives shortly before and during the period when players can obtain Aventurine • Waveflair through the limited Character Event Warp. The same Phase II lineup includes the limited 5-Star Light Cone “Summer Rides the Surf.”
| Version 4.5 Detail | Confirmed Information |

What Does “The Stoneheart’s Oath Ring” Mean?
The Stoneheart’s Oath Ring is one of the most important terms highlighted in the trailer’s official description. The wording places the ring directly inside the dangerous situation surrounding the IPC and suggests that even the Stonehearts’ established structures are vulnerable to the conflict.
The trailer doesn't provide enough information to treat every possible interpretation of the ring as confirmed lore. For readers tracking the story, it is better to view the ring as a major narrative clue rather than assume the trailer has already fulfilled its purpose.
Lies vs. Truth in “Deep Waters”
The trailer deliberately presents both lies and truth as dangerous, which is one of its clearest themes. A lie can protect someone temporarily, but revealing the truth can create a different kind of risk.
The official description asks who will have the final laugh once the masks come off. That wording suggests that the trailer is less concerned with a simple good-versus-bad conflict and more interested in hidden motives, information, and the consequences of exposing secrets.
This makes the banquet and secret-directive imagery particularly important. Both situations involve information that cannot be treated casually. Veiled threats surround one, while the other is designed to disappear immediately after being heard.
Full English Voice Cast for “Deep Waters”
The complete English voice cast includes characters from different parts of Honkai: Star Rail. The official credits list nine characters and their English performers.
The combination of IPC-linked figures and returning characters such as Himeko, Feixiao, Boothill, Argenti, and Dr. Ratio gives the trailer a wider connection to the game’s existing cast. However, appearing in the trailer does not by itself confirm that every listed character has a major role in the specific conflict.
At Animon Life, we typically see strong interest around official Honkai: Star Rail merchandise whenever major characters or new story developments receive promotional attention. The “Deep Waters” trailer adds another recognizable group of characters to that wider fan interest.
