If you’ve been digging into pre-release details for the upcoming open-world Arknights spinoff, you’ve probably stumbled on conversations around Arknights Endfield Chen lore. Longtime Arknights fans know Chen as the stoic, no-nonsense leader of the Lungmen Guard Department, but her appearance in Endfield has sparked tons of questions about how she fits into the new setting, hundreds of years after the events of the original game. I’ve spent months combing through official teasers, developer interviews, and cross-referencing original Arknights canon to put together the most accurate breakdown of her story so far. No baseless fan theories here, just confirmed details and well-supported context to help you understand her role before the game launches.
Chen’s Core Backstory Ties to Original Arknights Canon
Before we dive into Endfield-specific details, it helps to recap the key beats of the original Chen’s story that carry over to her descendant. The original Chen was a half-Lung, half-Victorian noble who worked her way up to lead Lungmen’s special ops unit, fighting to protect the city from both external threats and internal corruption. She wielded the legendary Chi Xiao sword, a family heirloom that could channel devastating fire-based Originium Arts, and had a complicated family history tied to both Lungmen’s ruling class and the Reunion movement leader Talulah.
You might be wondering how a character from the original Arknights timeline appears in Endfield, which is set on the entirely new continent of Talos-II long after the base game’s story. Official developers have confirmed she is a direct descendant of the original Chen from the base Arknights game, not a time-traveling version of the character you already know. The Chen in Endfield inherited both her ancestor’s surname and the Chi Xiao sword, passed down through 12 generations of the Chen family line.
That doesn’t mean she’s a carbon copy of the original, though. She grew up on Talos-II’s harsh frontier, not in the relatively civilized streets of Lungmen, so her priorities and lived experience are drastically different. She doesn’t carry the same baggage from the Reunion war or Lungmen’s political drama, but she does share her ancestor’s strict moral code and unshakable loyalty to the people under her protection.
Key Details Confirmed in Arknights Endfield Chen Lore Teasers
Developers have slowly dropped small lore crumbs about Endfield’s Chen across gameplay trailers, social media posts, and press interviews over the past year. We don’t have her full personal story yet, but these confirmed points give us a solid foundation for what to expect:
There are a lot of small, fun callbacks to the original Chen in these details too. For example, she still has a habit of overworking herself and skipping meals when she’s focused on a mission, a quirk that was a running gag with the original Chen’s co-workers in Lungmen. She also has the same characteristic Lung horn markings on her forehead, a clear visual tie to her draconic heritage.
Unlike the original Chen, she has no formal military or police training, and learned all her combat and leadership skills on the harsh frontier of Talos-II. That makes her fighting style far rougher and more improvisational than the precise, disciplined techniques the original Chen used. She’s also far more comfortable working with people from all backgrounds, from nomadic tribes to rogue scavengers, because she’s spent her whole life living and working alongside them.
Unresolved Lore Questions That Will Be Answered At Launch
For every detail we’ve gotten confirmed about Chen’s backstory, there are twice as many unanswered questions that developers are keeping under wraps until release. Some of these questions tie back to original Arknights canon, while others are specific to Endfield’s new setting.
One of the biggest fan debates right now centers on the shift in her Originium Arts alignment from fire to ice. The original Chen’s Chi Xiao sword channeled powerful fire attacks, but all gameplay footage of Endfield’s Chen shows her using ice-based Arts to freeze enemies and create barriers. Some fans theorize this means her family line merged with Talulah’s descendants at some point, since Talulah was known for her powerful ice Arts. Others think the shift comes from modifications made to the Chi Xiao sword to adapt to Talos-II’s unique Originium environment. We won’t know for sure until we can play through her personal story line.
Another big question is how much she knows about her famous ancestor. Official teasers show she has a small journal with notes about the original Chen and the history of the Chi Xiao sword, but it’s unclear if she knows the full details of her ancestor’s role in the Reunion war or the political history of old Terra. It’s also unclear if she has any living family members left, or if she’s the last remaining member of the Chen line on Talos-II.
We also don’t know the full details of the disaster that killed her old team. Teasers hint it’s tied to the same ancient ruins that serve as the game’s main story setting, and that the disaster is linked to the strange Originium anomalies popping up across Talos-II. Her personal story will likely tie directly into the game’s main narrative, so playing through her missions will be essential to understanding the full scope of Endfield’s plot.
What Chen’s Lore Means for Her Gameplay Role
You don’t have to care about lore to get value out of these details, because they directly hint at how Chen will play when you get to use her in game. Developers have repeatedly said that every character’s kit is designed to tie directly to their backstory, and Chen is no exception.
Based on her lore, you can expect her to be a top-tier pick for both exploration and high-difficulty combat content. As a Lead Supervisor with years of experience exploring Talos-II’s wilds, she’ll almost certainly have passive skills that make it easier to navigate harsh environments, spot hidden resources, and reduce the risk of random Originium anomaly encounters while you’re out exploring. For combat, her ice-based Arts and heavy sword mean she’ll work as both a durable frontline tank and a high-damage burst dealer, with skills that can freeze large groups of enemies to protect your team.
That means she's not the best pick for players who prefer fast, hit-and-run playstyles, but she shines in sustained fights where you need to tank damage while dishing out high burst. She’ll also likely have team buff skills that boost your whole party’s defense and exploration efficiency, which will make her a staple for any long exploration trips through high-level areas.
If you’re planning to main Chen when the game launches, there are a few small things you can do to prepare. First, don’t skip her personal story missions, even if you don’t care about lore. These missions will unlock exclusive upgrades for her Chi Xiao sword that you can’t get anywhere else, plus unique dialogue that fills in gaps in her backstory. Second, prioritize upgrading her defense and Art damage stats first, since those are the core of her kit. Third, keep an eye out for lore-related items hidden around the world, as many of them will unlock extra conversation scenes with Chen that add more depth to her story.
At the end of the day, Arknights Endfield Chen lore does a perfect job of honoring the legacy of one of Arknights’ most beloved characters while giving her a fresh, unique identity that fits the new setting. You don’t have to be a longtime Arknights fan to connect with her story of perseverance, loyalty, and searching for the truth, but long time fans will get tons of fun easter eggs and callbacks to the original game. As more official details drop ahead of launch, I’ll keep updating this guide with new confirmed lore points, so you can stay up to date before you start your first exploration run on Talos-II.
