Fire Emblem: Three Houses is about to become “four houses” with the upcoming release of the “Cindered Shadows” DLC. Nintendo dropped a trailer for the upcoming side story, part of the Wave 4 of Three Houses’ expansion pack, last Thursday. The DLC will introduce the “fourth house” of the Officers Academy: the Ashen Wolves, a secret house that has operated in the underground sewers of Garreg Mach Monastery for years.

Here is everything we know so far about Garreg Mach’s mysterious fourth house:

The Ashen Wolves

The Ashen Wolves is the name given to the collection of students that refer to themselves as the secret fourth house of the Officers Academy. They live in the Abyss, “the underground den of Fódlan’s outcasts” which is located in the sewers of Garreg Mach. Though the other houses in the Academy have eight members, it appears that the Ashen Wolves only have four. The four students that comprise the house are Yuri, Hapi, Constance, and Baltus.

In a scene in the Cindered Shadows trailer, Balthus is shown introducing himself and his friends to Byleth and their students. “Fine, we’re the Ashen Wolves,” he explains, “We’re the secret fourth house in Abyss. [The] surface world turned its back on us? We did the same in return.”

“The Ashen Wolves are a house in name alone,” continues Yuri, “They are eager students, with no teacher to guide them. If you could find it in your heart to take them under your wing, I would be most grateful.”

Their current motives are unknown, though it does appear that since it’s been confirmed that these students can be recruited and fight alongside Byleth and their students, they likely share a common enemy with the protagonists of Three Houses.

Yuri

Yuri is the leader of the Ashen Wolves house, and from his line of dialogue in the trailer, it appears he cares sincerely about his students. A leak from Japanese video game publication Famitsu confirmed that the aptly named house leader will be able to achieve an S-support romance with both Male and Female Byleth avatars. So far, fans have noticed the leader bears a resemblance to current Golden Deer student Lorenz, as the two both share purple hair and maintain a similar pose, with their right hand up at their chest and left hand on their hip.

In the trailer, Yuri is first shown using a sword in combat. Later on, he’s seen switching places with Byleth on the map during a battle, implying that he’s also adept at Faith magic.

Hapi

Constance

Constance is the first person in the trailer to explain what the Abyss is to Byleth and their students, dubbing it “the secret shadow of Garreg Mach.” She has short blonde hair with bangs, with purple streaks underneath. Additionally, the Famitsu leak claims that she will be able to support Edelgard from the Black Eagles.

She is part of a new fighting class in Three Houses called “Dark Flier”, who has the ability to use lances and wield dark Reason magic from her flying unit. “Tremble in fear at my magical might!” she yells at an enemy right before casting an ice-type spell towards them.
