Sirris of the Sunless Realms is one of the most tragic and compelling non-player characters encountered in Dark Souls 3. As a dedicated warrior bound by duty, her journey takes players through intricate side quests involving family tragedy and knightly loyalty. Understanding her background and progression steps ensures that players do not accidentally lock themselves out of her exclusive rewards.

Initial Encounters and How to Start Her Quest

Players first meet Sirris at Firelink Shrine after lighting the Halfway Fortress bonfire in the Road of Sacrifices. Initial interactions are brief, as she acts distant toward the player until they prove their worth. To progress her storyline, you must find the Dreamchaser's Ashes in Farron Keep and hand them over to the Shrine Handmaid.

Returning to Firelink Shrine after delivering the ashes triggers a new dialogue with Sirris. She acknowledges your gentle nature and grants you the Darkmoon Loyalty gesture. This step unlocks her cooperation, making her available as a helpful summon for key boss battles.

Assisting Sirris in Combat Encounters

Her narrative advances significantly upon reaching Irithyll of the Boreal Valley. Cross the main bridge and reload the area to discover her red summon sign near the entry barrier. Entering her world allows you to assist her in defeating Creighton the Wanderer, a dangerous Dark Spirit.

After defeating Creighton, Sirris will thank you back at Firelink Shrine by offering the Silvercat Ring and a Blessed Mail Breaker. Players should exercise caution, as offering Pale Tongues to Rosaria at any point during this questline will turn Sirris permanently hostile.

The Final Confrontation and Knightly Vow

The climax of her questline involves defeating Aldrich, Devourer of Gods, and returning to the Pit of Hollows in the Undead Settlement. Outside the Curse-rotted Greatwood arena, another summon sign allows players to assist Sirris against her own grandfather, Holy Knight Hodrick. Helping her achieve victory finally allows her grandfather to rest in peace.

Upon returning to Firelink Shrine, Sirris will request to swear a vow of knighthood to you. Accepting her proposal enables her assistance during late-game encounters, including the Twin Princes battle. Ultimately, her journey concludes quietly outside Firelink Shrine, leaving behind her gear for the player to collect.
