The Goddess of Winter and Mother of the flock, the forgotten god of lambs who calls the Lamb home to Woolhaven.
Yngya is the one god in Cult of the Lamb who actually belongs to the Lamb. The whole base game runs on Narinder's bargain, but the Goddess of Winter is the forgotten deity of lambs, the Mother of the flock who summons the last of her kind home.
She is an ancient deity and the ruler of Woolhaven, the central character of the Woolhaven DLC. Per the wiki, she is the Goddess of Winter and the second major boss of The Rot biome, a giant winter sheep crowned with snowflakes whose voice sounds like music.
Her story is a homecoming gone wrong. According to the wiki she calls the Lamb back to Woolhaven, the home of the lambs, before the Rot corrupts her into the fleshy horror the Lamb has to face.
This guide covers who Yngya is, her summons to Woolhaven, the Rot that turns her into a boss, her many forms, and how recruiting her earns Yngya's Fleece.

Finish her quest to add her as a follower and receive Yngya's Fleece.Yngya is the Goddess of Winter and, per the wiki, the forgotten deity of lambs. She is an ancient deity and the ruler of Woolhaven, the central figure of the entire Woolhaven DLC and the second major boss of The Rot biome.
Her base form is a winter god made of contradictions. According to the wiki she is a giant sheep with eight horns on each side of her head, multiple eyes including a black central one, a black mountain-shaped crown topped with a snowflake, and a silver bell at her neck. Her voice, the wiki notes, sounds like music.
She is the Lamb's own god, not 
Narinder. Where the base game has the Lamb serve the god of Death, Yngya is the Mother of the flock who calls the last lamb home, a separate divinity tied to the Lamb's lost kind. For the rest of the cast, see the full Cult of the Lamb characters roster.
Yngya opens the Woolhaven DLC by calling the Lamb home. Per the wiki she summons the player as "the last of the lambs," telling them she has waited in the frost and silence and that the mountain calls them home.
That home is Woolhaven, which the wiki describes as the home of the lambs. As the Mother of the flock, Yngya frames the Lamb's journey up the mountain as a return to their own forgotten people rather than another errand for a foreign god.
The climb runs through the Rot. The wiki's dialogue covers a Rotburn collection quest, encounters with the rancher Baraq, and the road that eventually sends the Lamb against 
Marchosias and his Free Pack on Yngya's behalf.
Yngya is not just a quest-giver; she is corrupted into a boss. Per the wiki she is the second major boss of The Rot biome, and the rot twists her serene winter form into something monstrous.
The wiki documents that corruption in detail. Her Shrine Form Rotten turns her body fleshy and reddish-orange with protrusions, her collar becomes an intestinal structure, and teeth grow from her ears, a grim inversion of the snow-covered goddess who summoned the Lamb.
Her corpse marks the cost. The wiki includes 
the Corpse of Yngya among her imagery, and the 
Yngya's Torment relic ties the goddess to the rot that consumed Woolhaven. She is a god brought low by the same blight the Lamb is sent to cleanse.
Yngya appears in more forms than almost any character in the game. The wiki lists Base Form, Shrine Form, Shrine Form Rotten, Eldritch Form Rotten, and a Follower Form, tracking her arc from goddess to corrupted boss to cult member.

The shape she takes if recruited, joining the Lamb's cult as a follower after her questline.The forms tell the DLC's whole story. A god of winter and lambs, frozen in death, is woken, rotted, fought, and finally folded into the very cult her summons set in motion.
Recruited Yngya is a follower with her own quest chain. Per the wiki she gives the Lamb two special missions once she joins.
The first is a ritual, and the second is a journey. According to the wiki, the second mission has Yngya travel to Woolhaven for a special dialogue with the Lamb, and at the end of it she gives them Yngya's Fleece, a reward fitting for the goddess of the flock.
She also reacts to wool. The wiki notes Yngya has unique dialogue if you give her wool through the follower commands menu, a small touch that keeps the Goddess of Winter connected to the Woolhaven theme even as a rank-and-file cultist. In practice, finishing her missions is worth it for the fleece alone.
Yngya's title hides the twist of the DLC. She is the "Mother of the flock," the forgotten god of the Lamb's own kind, which reframes Woolhaven as a homecoming rather than another conquest for a borrowed deity.
Her music is literal. The wiki notes that Yngya's voice sounds like music, fitting for a winter goddess whose summons reads like a hymn, calling the lost lamb back through frost and silence to the mountain that was always home.
Yngya is the heart of the Woolhaven DLC. These guides cover the expansion, her fleece, and the bosses of the mountain.
