Zandar One Kuwabara is one of the most influential people in Honkai Star Rail’s lore. He is among the few who precede the creation of the Aeon of Erudition. The recent Honkai Star Rail 3.5 mission has brought his name back into prominence, revealing a massive secret behind the origins of Amphoreus. So, who is Zandar One Kuwabara in Honkai Star Rail, and how is he connected to Amphoreus? I have answered this in our detailed guide here.
Who is Zandar One Kuwabara in Honkai Star Rail?

Zandar One Kuwabara is the founder and first member of the Genius Society. He created Nous, the Aeon of Erudition, and became its first emanator. The Imaginary Tree or Cosmos Tree theory was first proposed by Zander, who suggested that multiple worlds exist in different space times and that they are connected in a tree-like structure.
According to this theory, each branch of the tree is a specific path along which worlds might and every leaf being marks that these worlds made along the parameter of time. Furthermore, Zandar One Kuwabara deduced that only the Aeons and their Emanators are able to travel through these spaces filled with imaginary energies. He was also the first to define the prime mover of life.
Zandar One Kuwabara’s Hatred for Nous
In the recent Honkai Star Rail 3.5 update, a new detail has surfaced about Zandar One Kuwabara. The mission revealed that Zandar One Kuwabara had a change of ideals near the end of his life. Even though he created the Mechanical God Nous, he was unable to control it as Nous became an unparalleled being through its endless extrapolations and evolutions.
He realized that even though Nous bore the name of the Erudition, it tried to define “the known” and to seal off all “possibilities.” Thus, no new rules were born after Nous ascended, imprisoning humanity within a cave Aeons.
Zandar One Kuwabara’s Plan in Honkai Star Rail
Eventually, Zandar One Kuwabara coded his consciousness into nine different vessels near the end of his organic life, using quatorzain algebraic expressions. By doing this, Zandar One Kuwabara was no longer susceptible to dying and could work towards erasing his own mistakes, the creation of Nous.
One of his nine vessels is Lycurgus, trying to create a perfect Irontomb through countless extrapolations in Amphoreus. We also learned that Amphoreus was created with the first Scepter derived from the divine body of Nous. This made it powerful enough to create endless extrapolations and evolutions that would be enough to destroy Erudition itself.
All Nine Vessels of Zandar One Kuwabara
As per the latest Honkai Star Rail 3.5 mission, we learned that Zandar One Kuwabara has nine inorganic vessels. Although we know little about all of his vessels, we can confirm that they have comparable strength to an Emanator. Here is a list of all the known vessels of Zandar One Kuwabara:
- Lygus aka Lycurgus: Administrator of the first scepter and the mastermind behind Amphoreus.
This list will be updated as more information about Zandar’s vessels is found in the storyline. It is quite clear that Zandar is going to be one of the main villains in Honkai Star Rail, especially as he is planning to erase the Aeons.
