As Gilles' Noble Phantasm engulf the tower of the Dragon Witch, Gwen decides to deal with it while the Chaldeans rush in and fight against the Witch to end this Singularity.
Gwen knew what was at stake here, and she knew well what she was facing.
Gilles' Noble Phantasm was somehow affected by the Black Mist, something that baffled the seamstress, how was that thing in here? After Viego's defeat, that thing should be contained inside the Shadow Isles, but that didn't matter right now.
What mattered was stopping it, and she had a plan.
While Ritsuka and the rest went to fight the Dragon Witch, it would be Gwen's job to take down this beast. No matter, she took down bigger and badder during the Harrowing, so this shouldn't be a problem, right?
"C'mon Gwen, you know what to do, just do it!" - the girl said to herself, getting ready to strike.
Holding her scissors, she jumped and landed on one of the tentacles of the creature while it took no importance to her. She took this as an opportunity, slicing the tentacles with precision and skill.
While the smallest ones were no trouble for her, the big ones were, and as soon as the monster took notice of her, things quickly started to spiral out of control.
From its mouth, Black Mist started to spew everywhere, releasing beasts that she had not seen ever since the Ruination back in Runeterra.
Camavoran soldiers emerged and charged towards Gwen, skillfully moving towards her and attacking with spears and arrows that she avoided by using Hallowed Mist.
"Darn it! Those things as well? Need to take care of them or this will be 10 times harder!" - Gwen said as she jumped high in the air, preparing to attack.
As she dropped, her scissors started to make quick work of the soldiers, taking them on 1 by 1. Her needles were used to impale them and cleanse them from the Black Mist, making them disappear and clearing a path for Gwen towards the mouth of the giant creature that was Gilles' NP.
As she got closer, the number of Camavoran soldiers increased little by little and soon they started to overwhelm the girl, aided by the fact that from the Mist, 3 Camavoran Dragons emerged and started to fire upon the girl with their gastly breaths.
Gwen, seeing herself surrounded, used her needles to purify the entire area with Hallowed Mist, allowing her to temporarily drive off her enemies while still making her way towards the core of the giant Noble Phantasm.
"Just... A bit more!" - the girl screamed as she jumped in between the ghost soldiers to reach her objective, but before she could, something else jumped from the inside of the creature.
A knight, but not like the Camavorean ones, this one had a black armor and it was holding a sword which Gwen could feel had a strange magic, one corrupted by the Black Mist. This one, in difference to the others, could speak, but only one word as understandable.
"ARRRRTHUUUUUUUUUUR!" - the knight yelled before striking Gwen so fast it nearly threw her off the creature.
As soon as Gwen got a chance to stand up, she looked at the knight before launching her needles against him with the intent of cleansing the Black Mist.
"Listen, you're not yourself, you're being controlled! Stay still and I'll help you!" - Gwen said, attempting to calm the knight and make the process easier, but her words fell to deaf ears.
Strengthened by the Black Mist, the knight broke free from his restraints and attacked Gwen, who, seeing this, decided to subdue him by force before cleansing him.
Lucky for the girl, the Camavorean soldiers seemed to be retreating while she was fighting the knight, like the Black Mist forced them to give way to its champion.
The black knight launched a hit with his sword, which Gwen managed to block with her scissors before dashing behind her enemy and trying to stab him, but was blocked by the armor and nearly took a slash in the chest.
Powering her scissors with the Hallowed Mist, Gwen once again clashed against the knight, but this time she managed to keep her ground a bit better and she could push her enemy back with her swings.
Launching one of her needles, she managed to pierce through the armor of the knight in his arm, which threw him off balance slightly and allowed her to get a couple of good hits in before having to back down once again.
She then witnessed the knight pulling up a strange weapon she had no knowledge of before starting to shoot at her with it, with Gwen reacting as fast as she could, pulling her Hallowed Mist and making the shots pass through her body like nothing.
Seeing this, the knight stopped shooting and closed the gap between the two incredibly fast, hitting her before shooting once again, with the shots managing to pierce the girl this time, with her 'bleeding' the Hallowed Mist from her wounds.
With her enemy's strength and speed being clearly superior, Gwen decided to finish the fight as fast as she could, with her recently gained Noble Phantasm.
"My creator is still with me, her soul is one with mine, her wish is one I'll always follow. By my power, evil shall disappear! Needles of the Hallowed Lands!" -
Her 9 needles were shot directly at her enemy, piercing its body and allowing Gwen to close in, forcing the knight on his knees and starting to purify him, but as she was doing so, she heard a voice, a voice she hoped she'd never hear again.
"My Mist shall follow you forever doll" - the ominous voice came from the knight mere seconds before the Black Mist was cleansed from him, with his body dissolving in a golden glow.
Gwen stayed a few seconds without moving, in shock. She knew who that voice belonged to, but it should be impossible for HIM to be free, only someone with the same talents as her or Isolde could bring him back.
She needed to think about this, but now it wasn't the moment, she had to deal with the matter at hand, and with the Camavorean soldiers still not moving, she took this chance to use her needles to remove the Black Mist from Gilles' Noble Phantasm.
With the Mist gone, the giant creature started to disappear, with Gwen returning to the building.
"I hope they did their part of the job" - Gwen stated.
She then made her way towards the Dragon Witch's room, with her nowhere to be seen, and with Ritsuka holding a golden cup in his hands.
"Seems like this wasn't too hard for you" - Gwen said as she joined them in the room - "But where is she?" -
"We took her down and she dissolved, so we retrieved the Holy Grail" - Ritsuka stated - "I see you did your job as well, thanks Gwen" -
"I always fulfill my promises, better remember that" -
With that, the Servants in the room started to dissolve as well. Their mission was over, and now they would return to the Throne, not before they told the Master to summon them back when they returned.
However, Gwen didn't disappear like the others, she simply stayed there, leaving Ritsuka and Mash confused as to what was going on, but their confusion didn't last as the process of RayShifting them back to Chaldea started.
Chaldea
"Good job you two, things weren't so hard right?" - a man with a doctor's attire asked the two.
"A bit, but we managed to pull through, thanks for your guidance Doctor Roman" - Ritsuka said while getting off the coffin.
"No problem, but, um... Why do you have a doll on your hands?" -
In Fujimaru's left hand, he was holding a small doll with light blue hair which started to tremble and emit a blue mist before falling and in a small flash, transforming into... Gwen.
"Ouch, what was that? This place is... Oh, Ritsuka, Mash, hello!" - the girl said with joy - "Could you tell me where we are?" -
Everyone was utterly confused at her presence, but in a way, Ritsuka and Mash felt... Calm with her around.
Whatever the case, one thing was certain.
The Hallowed Seamstress had arrived at Chaldea.
And she was there to stay.
