The Numbers Don"t Lie: Welt"s Confirmed Age
Let"s break this down because I"ve seen way too much confusion in the community about this. Welt Yang is definitively 82 years old during HSR"s timeline.
Born in 1947, with the game"s events happening around 2029—do the math and you get 82 years. Simple as that. But here"s where it gets interesting (and honestly, pretty tragic when you think about it).
His birth name was Joachim Nokianvirtanen. Parents were Elias Nokianvirtanen and Henrietta Yang—keep that Yang surname in mind, it becomes important later. The kid"s life took a hard left turn in November 1955 when he was just 8 years old. That"s when he witnessed the Thanksgiving Disaster in New York, watching Welt Joyce sacrifice himself and pass the Herrscher of Reason Core to little Joachim.
Fast forward to February 1st, 2000—this is where things get wild. During the Second Eruption in Siberia, Welt fought Sirin and his body got completely destroyed. We"re talking obliterated. But his consciousness? That survived in the Herrscher Core, which is both fascinating and terrifying from a lore perspective.
What really throws people off is his appearance. The guy looks like he"s in his 30s or early 40s, standing at 180 cm (putting him in that “Tall Male” category with Blade, Jing Yuan, and Gepard). Those youthful features aren"t just good genes—they"re the result of his Herrscher abilities literally reconstructing his body cell by cell. New physical form, same memories and consciousness.
Welt"s Background: Universe-Hopping 101
Here"s what makes Welt unique in the HSR roster—he"s not some alternate universe version or dimensional variant. This is the actual, canonical continuation from Honkai Impact 3rd. When he drops references to Kevin Kaslana or Project STIGMA in conversations with Acheron, he"s talking from personal experience.
The man recognizes Luocha as a version of Otto Apocalypse, which tells you everything about his knowledge of the original world"s events. We"re talking about a former Anti-Entropy Sovereign who saved Earth from annihilation multiple times. After the Honkai threat got sealed away, what does this legendary warrior do? Retires to work as an animation storyboard artist at E.T. Studio. Created the entire “Arahato” mecha anime franchise to help fund Anti-Entropy operations—honestly, that"s kind of brilliant.
His Herrscher of Reason power is called “Creation,” and it"s exactly what it sounds like. He can recreate anything as long as he understands the underlying concepts. In combat, this manifests as gravity manipulation through his Star of Eden cane. That Ultimate move “Synthetic Black Hole”? It doesn"t just look cool—it imprisons enemies, reduces their speed by 10%, and delays their actions.
After the St. Fountain Incident, he traveled through a space portal with Void Archives to stop Sky People invasions. Which brings us to how he ended up on the Express in the first place.
The Joyce vs Yang Mix-Up (And Why It Matters)
This is where I see the most confusion, so let"s clear it up once and for all.
Welt Yang and Welt Joyce are completely different people. Yang is Joyce"s successor, taking over after Joyce"s sacrifice during the Thanksgiving Disaster. When Joyce transferred the Herrscher Core to 8-year-old Joachim, he also passed along the title and the responsibility of protecting humanity.
Yang adopted the name “Welt Yang” using his mother"s surname to honor his predecessor while maintaining his own identity. It"s actually pretty touching when you think about it. Joyce had a relationship with Reanna Brigantia, while Yang never married—though he did adopt a son named Joffrey Joyce Yang. Notice how he used Joyce"s name as the middle name? That"s not coincidence.
How Welt Found His Way to the Astral Express
Himeko and Pom-Pom discovered him stranded on planet Salsotto after his conflict with the Sky People. His companion Void Archives left the Express during their travels—we don"t get much detail on why, but knowing Void Archives, it probably wasn"t a tearful goodbye.
What I find interesting about Welt"s transition to the Express is how it represents genuine character growth. He went from being this fate-burdened protector carrying the weight of worlds to someone who could freely choose his own path. The guy naturally fell into a mentor role for the Trailblazer, March 7th, and Dan Heng—and honestly, with his experience, who else would?
Himeko notes that he seems “young at heart” despite being 82, which explains how he connects so well with the younger crew while providing that stability they need.
Age Gaps That"ll Make You Feel Young
Let"s put Welt"s 82 years in perspective with the rest of the Astral Express crew.
He significantly outages all the human members. Himeko"s estimated to be in her early-to-mid 30s—that"s roughly 50 years younger than Welt. Dan Heng, March 7th, and the Trailblazer appear to be in their late teens or early 20s. Welt"s literally old enough to be their grandfather multiple times over.
In the Chinese voice-over, March 7th calls him “Uncle Yang” (杨叔 Yáng shū), which perfectly captures that familial dynamic. The age gap establishes clear generational differences and positions Welt as this bridge between different eras of the universe"s history.
Timeline Deep-Dive: The Canonical Evidence
The HoYoverse Universe Index wiki provides the comprehensive chronological breakdown: 1947 birth, 1955 Thanksgiving Disaster, Anti-Entropy leadership, eventual departure from Earth. Game dialogues reference his interactions with Kevin Kaslana and Otto Apocalypse, plus his relationship with his successor Bronya.
Here"s a detail that really shows the toll his journey took: in 2005, he"d only recovered 65% of his original strength after body reconstruction. By 2017, his consciousness existing in the Core allowed him to reconstruct his body again to defend Bronya from Kevin Kaslana in the Sea of Quanta.
The cross-game continuity makes Welt a confirmed universe traveler between Honkai Impact 3rd and Star Rail. His character story reveals he views the Trailblazer as a “classic cartoon protagonist”—which makes sense given his animation background and analytical nature.
Debunking the Age Theories
I"ve seen some wild theories in the community, so let"s address the biggest misconceptions.
First, those alternative timeline theories? Debunked by the canonical 1947 birth year calculation. Some players confuse Welt Yang with Joyce or misunderstand how the Herrscher reconstruction process works, leading to false theories about his age.
Translation discrepancies sometimes show 80 vs 82 years, but detailed timeline sources consistently support 82 based on specific event dates. The most persistent misconception is assuming his physical appearance indicates his chronological age—completely missing the crucial lore about how his Herrscher abilities explain those youthful looks.
Character Development: From Burden to Freedom
Welt"s advanced age positions him as the primary mentor and strategic advisor, but his character arc is what makes him compelling. His Anti-Entropy leadership experience provides organizational skills and tactical knowledge that the crew desperately needs.
What I love about his development is the emotional growth from reluctant, destiny-burdened hero to willing adventurer. His character story emphasizes this transformation perfectly: “This time, there is no burden or destiny to bear. Everything shall obey his own will.”
His mentoring style emphasizes teaching through experience rather than direct instruction. He encourages independent problem-solving while providing safety nets—exactly what you"d expect from someone who"s seen multiple generations of heroes rise and fall.
