Arknights: Endfield Characters’ Ages and Birthdays

A list of the ages and birthdays of all Arknights: Endfield characters. The data is based on lore, in-game dialogues, artworks, videos, some official info, character appearances, and educated guesses.
Gryphline has released only limited info on the ages of all the characters in Arknights: Endfield, so this list is mostly a guesswork based on cinematics, artworks, comparisons between characters and real-life people, and a close analysis of the game’s lore, including each character’s background and the game world.
This list provides approximate ages for most characters, so please note that many of them are not canon.
I usually include estimated heights by comparing in-game character models. However, in this case, several models appear to have been reused across different characters, making it difficult to determine accurate height differences.
If you notice that I am missing the age of an Arknights: Endfield character on which we have official info, please contact me and provide the source. I will add them to the list as soon as possible.
Ages - from youngest to oldest
Juniors
Rossi: 14-15
Rossi is fficially noted as not yet of age. Lore states she fought her first battle at 11 and took her first mercenary job at 13. Her dialogue and behavior in the Endfield Hub confirm she is treated as the youngest of the team.
Lifeng: 16
Lifeng is listed as an intern from the Wuling City Guards. His prosthetic arm is a result of an incident 10 years ago, which is a major part of his growth story.
Young adults
Last Rite: 18-19
Last Rite is described as a fresh recruit who recently left a protégé role. She still struggles with the corporate terminology of her previous employment, suggesting she is at the very start of her career.
Chen Qianyu: 20
Born in Year 132 (Talos Calendar); the current year is 152. Chen Qianyu’s profile explicitly states her birth year, making her one of the few with a fixed biological age.
Tangtang: 21
Though highly childish and energetic, Tangtang is confirmed to be over 18 and works as a full-time engineering apprentice.
Xaihi: 22
Xaihi’s appearance is ambiguous (about 15-22), but her role as a specialist and her combat experience suggest she is in her early 20s.
Perlica: 24-27
The lore confirms Perlica was a young child during the Ten-Year War, which ended exactly 10 years ago. As a supervisor, she is best placed in her mid-to-late 20s.
Wulfgard: 21-24
Wulfgard is a young mercenary leader. He was active when Rossi was a child, placing him a few years ahead of her.
Snowshine: 22-29
Estella: 22-29
Fluorite: 22-29
Yvonne: 22-29
Alesh: 22-29
Arclight: 22-29
Akekuri: 22-29
Catcher: 22-29
According to the lore, these operators have training, university-level expertise, or years of field experience; therefore, they all fall within the young adult age range.
Veterans
Ember: 32-35
Ember is an Oathkeeper Knight and veteran instructor. She has enough seniority to act as the primary combat mentor for the newer recruits.
Avywenna: 35-38
Avywenna is a former corporate professional who spent years in the “neon-lit cities” before retiring to the frontier. She has the demeanor of a mature, experienced woman.
Da Pan: around 45
Da Pan is physically presented as a middle-aged, grizzled warrior. His dialogue is full of “old soldier” wisdom.
Antal: 60-150
The lore is slightly contradictory: Antal is called a young Savra in some files but a wizened tribal elder in others. In the Arknights universe, some Savra can live up to 150 years, and Antal’s physical model is significantly more aged than others.
Ancients
Endministrator: physically 25, chronologically 152+
The Endministrator arrived on Talos-II as a Pioneer during the initial colonization. Most of that time was spent in a Sarcophagus (stasis), meaning the body has not aged, but the existence dates back to the very beginning of the planet’s human history.
Pogranichnik: physically 60+, chronologically 152-500+
As a Reconvener, Pogranichnik is a biological copy of a hero from the past. He possesses memories of The Great Trek (150 years ago) and potentially The Era of Terra (500 years ago).
Ardelia: physically 18-22, chronologically 500+
Gilberta: physically 18-22, chronologically 500+
Laevatain: physically 18-22, chronologically 500+
These characters are reconstructions of people who lived on Terra during the original Arknights timeline.
