Over the years, Dark Souls fans have gotten used to depressing storylines. Whether it's the doomed Catarina family in the original game, Lucatiel of Mirrah's slow descent into madness from Dark Souls II, or Eileen the Crow's suicide mission in Bloodborne, From Software has made a habit of creating lovable characters and dragging them through the mud.
Dark Souls III (somewhat predictably) continues this tradition: it may take players some time to find her, but Sirris of the Sunless Realms' story isn't exactly upbeat. On the plus side, her questline is also one of the best in the game: instead of simply searching for a static NPC at certain points throughout the story, Sirris actually takes on an active role.
In typical Dark Souls fashion, however, figuring out how and when to aid Sirris in her quest can be a backwards, immensely confusing task - unless you know where to go and what to look for. That's where this guide comes in - but first:
SPOILER WARNING!
If you hadn't already guessed, we'll be talking about the end of Sirris' storyline - if you want to try and figure it out on your own, bookmark this guide and come back if you need help.
In The Halfway Fortress
Again, you'll have to proceed through the game until you reach the ruins of Anor Londo and kill Aldritch of the Deep. Once you do, head back to the Undead Settlement and find the Curse-Rotted Greatwood's arena. Before you go warping straight to the Pit of Hollows bonfire, know that Sirris' next summon sign will be in the hallway just before the boss fight - instead, use the Dilapidated Bridge or Cliff Underside bonfires and just run past any enemies.
You'll be taking on Holy Knight Hodrick again (assuming he invaded your game earlier), but at least you have Sirris on your side this time. Take Hodrick down, and Sirris will return to Firelink Shrine yet again.
Here, Sirris will offer her services as a knight. If you decline, you can find her completely Hollowed and hostile back in the Pit of Hollows. However, if you accept, she'll thank you and continue to help with any boss fights you summon her to.
In The Cemetery Of Ash
Unfortunately, Sirris' story doesn't have a very happy ending.
After defeating Prince Lothric and his elder brother Lorian (which you can summon Sirris for), you'll find her body in front of her grandfather's grave just outside of the Firelink Shrine.
It's a shame that Sirris can't live to see the linking of the First Flame, but at the very least, she leaves her Sunless Talisman for you to use.
Sure, Sirris' quest for redemption doesn't have a very uplifting ending, but there are a few NPCs that can make it through the full game - if you're looking for a more uplifting sidequest, check out our guide to Siegward of Catarina's story!
