In this guide, we’ll dive deep into the data bank records and character dialogues to settle the confusion. We’ll explore the origins of the Ever-Burning Star, the role of the IPC in planetary rebranding, and finally answer the question, is Edo Star Benzaitengoku, or is there a bigger mystery waiting to be uncovered?

What is Benzaitengoku?

In the world of Honkai Star Rail, Benzaitengoku is known as a legendary paradise of entertainment and culture.

The name comes from Japanese mythology, combining “benzaiten” (the goddess of music and words) and “tengoku” (meaning heaven). Together, the name literally means a “Heavenly Place of Arts.” Because it is a world where creativity has reached its peak, it is a very important place for followers of The Elation.

Many ancient records found on the Herta Space Station and the Xianzhou Luofu call Benzaitengoku the “Ever-Burning Star.” They describe it as a glowing planet that acts as a lighthouse for artists and scholars across the galaxy.

The planet has a chaotic history. It was originally created by Aha, the Aeon of Elation, as a giant stage for performers. The world centered around a living moon where grand games were held. Those who won these games were given divine power by the Aeon of Elation.

The planet’s golden age almost ended in total destruction. During the expansion of the Antimatter Legion, the army of Destruction swept through the area and burned everything.

Benzaitengoku was only saved by a miracle when an artist captured the entire world within a painting scroll. This kept the people and their culture safe within a flat, two-dimensional world while the real planet burned to ashes.

Years later, survivors tried to rebuild their home. This was made possible by the Interastral Peace Corporation (IPC), which used advanced technology to pull the world out of the painting and back into reality.

After the IPC provided the technology and money to restore the planet, they officially changed the name of Benzaitengoku to Planarcadia.

For Trailblazers, Benzaitengoku is most important because it is where the Astral Express once crashed and was abandoned for a long time. It wasn’t until Himeko found the train and repaired it that the journey of the Express officially restarted.

Is Edo Star Benzaitengoku? Are Edo Star and Benzaitengoku the same?

With so many legendary planets in the cosmos, many players find themselves asking, “Is Edo Star Benzaitengoku?” While both worlds share themes of art and music, the short answer is no. They are two entirely different planets with distinct histories in the Honkai Star Rail universe.

Edo Star is a planet nestled within a vast ion storm. It first gained major attention during the Penacony questline while the crew was trapped in Ena’s Dream. Pom-Pom listed it as a potential next destination, noting that it was under assault by the Antimatter Legion.

While the IPC initially requested the Trailblazers to investigate because distress signals had ceased, it was later revealed in the Amphoreus missions that Edo Star managed to repel the Legion and has since entered a temporary lockdown.

On the other hand, Benzaitengoku is the former name of Planarcadia. It is a world tied deeply to Aha and the Path of Elation. It is famous for being saved within a painting and later restored by the IPC.

So, is Edo Star Benzaitengoku? Definitely not. Edo Star is known for its houses of music and ancient ballads, while Benzaitengoku (now Planarcadia) is an IPC asset planet known for its entertainment and culture.

While the mystery of “Is Edo Star Benzaitengoku?” has been settled, many players are still wondering what actually happened to Edo Star. As of writing, Edo Star is inaccessible to the Astral Express.

While Edo Star successfully repelled the Antimatter Legion, the IPC placed the entire world under a temporary lockdown. With distress signals silenced and the borders closed, there is no way for the Express to make a stop there.

Rather than attempting to brave the dangerous ion storms to reach a locked-down Edo Star, the crew of the Astral Express decided to pivot toward Planarcadia. Following the grueling events in Amphoreus, the Express was in desperate need of a highly developed world to restock essential supplies.

As a thriving asset planet under the IPC, Planarcadia offered the perfect infrastructure for the crew to refuel and replenish their resources for the journey ahead.

The specific suggestion to visit Planarcadia came from Jade of the IPC’s Ten Stonehearts. She pointed out that the planet’s Phantasmoon was entering its full phase once again, a rare event that signals the start of the legendary grand games.

Beyond logistics, the trip also serves as a deeply personal journey for Himeko. Planarcadia is the historic site where she first discovered and repaired the abandoned Astral Express years ago. With the moon waxing full and the world thriving once more, it was time for Himeko to return to the place she considers her homeland.

While Edo Star remains a closed-off mystery for now, the Trailblaze continues on Planarcadia.
