First released in 2021, Delusion Puppets tells the story of Diluc falling into the hands of the Fatui and becoming one of their members. After an undisclosed failed mission, Tartaglia is gravely injured, allowing the Doctor to take advantage of his condition and experiment on him. Eventually, the same fate befalls Diluc.
With their Visions confiscated, both are brainwashed and implanted with a control mechanism attached to their spines. Diluc and Tartaglia are placed in a separate rank within the Fatui, known as Delusion Puppets—special soldiers capable of wielding Delusions without suffering their usual side effects, making them perfect, emotionless killing machines.
However, due to their unique nature, Diluc and Tartaglia are not fully controlled, leading to unstable minds, violent tendencies, and memory loss.
2.Nocturnal
A journey after the end.
1,500 years have passed since Diluc and Tartaglia achieved perfect immortality. However, an unknown event causes Tartaglia to lose his physical body. During this time, Diluc has become known as Bloodrover, while Tartaglia is referred to as Eclipse.
A century after Eclipse's disappearance, the Monoceros Caeli suddenly falls from Teyvat’s sky. This event awakens Diluc, the blind hunter, who has been in a deep slumber, mourning the loss of his lover.
Tartaglia reappears in spiritual form when Diluc retrieves the first constellation—a star piece stored in a capsule within Diluc’s left eye socket. In this form, Tartaglia has no memories and lacks a physical body. The exact circumstances of his condition remain a mystery.
Believing that collecting Tartaglia’s constellations will restore his memories and power, Diluc embarks on a journey to recover the fallen stars with the help of an old friend, Zhongli—the Synchronic.
HALF-ALTERNATIVE UNIVERSE
RIFT WORKS (IMPERFECT IMMORTALITY)
RIFT is a compilation of stories featuring the reincarnation of Diluc and Tartaglia after The Celestial Cleanse. The series follows two main routes:
Bad Route: RIFT: Canis (Set in the original Genshin Impact universe)
Good Route: RIFT: Insomnia (Multiple reincarnations in different worlds and universes)
The core theme of RIFT revolves around reincarnation and eternal lovers. Most of the time, only one of them retains memories of their past lives, forming what you can call Imperfect Immortality”.
In addition to their curses, Tartaglia also suffers from what Diluc calls the Illusion of Eternal Youth. In every reincarnation, regardless of Diluc’s varying ages, Tartaglia always appears in his prime (between 19-27 years old) and dies due to various circumstances. This creates the illusion of eternal youth, but in reality, Tartaglia never gets the chance to grow old.
A simple way to distinguish between the routes: In the bad route, Tartaglia bears Roman numerals and has a missing eye, while Diluc is seen wearing his usual bartender attire. The Lapis duo from the Zhongchi universe also make appearances in RIFT: Canis.
Some RIFT stories may be rewritten and included in the AU section.
2.HEARTSEEKER (Wonderland AU)
Heartseeker takes place in a Wonderland-inspired version of Teyvat. Fourteen-year-old Diluc, while chasing a fox, falls down a well and finds himself in Wonderland. To return home, he must meet the leaders of each Card House and gain their favor.
The Jack Knight, Tartaglia, was the ginger fox Diluc had been chasing. Upon their reunion, Tartaglia feels responsible for leading Diluc into this world and decides to accompany him on his journey.
Ultimately, Heartseeker serves as a prelude to the betrayal and tragedy that will befall Diluc in the original world.
3.MIDNIGHT MUSE
A collaboration between Tequillavie (concept) and Kae_karo (writer).
In Midnight Muse, Tartaglia’s consciousness from Delusion Puppets is swapped with another version of himself from RIFT: Canis. At this point, Diluc and Tartaglia from Delusion Puppets are beginning to acknowledge their feelings for each other but struggle to accept them.
This event serves as a catalyst that ultimately strengthens their bond.
Midnight Muse is considered part of both series.
ALTERNATIVE UNIVERSE
CHROMATIC ABERRATION: WHAT IF
An Omegaverse vintage AU centering around a love triangle between Diluc, Zhongli, and Tartaglia (Ajax). In the original version, Tartaglia marries Zhongli. However, in What IF, he marries Diluc instead.
2.THE ANGEL FORMULA
Originally an annual Valentine’s release, The Angel Formula is a dark fantasy story exploring the existence of Angels—beautiful, humanoid spiritual beings devoid of emotions or substance.
An Angel can manifest a physical body only by consuming a human heart. In this case, Tartaglia devours Diluc’s heart. However, Diluc miraculously survives and, instead of perishing, captures and imprisons the Angel who took his heart.
Ultimately, The Angel Formula is the fevered dream of a sick man haunted by the death of his lover.
-----------------------------------------------
All stamp art belongs to Fanbook: Somnolence. I will talk about their meaning one day.
In the linework ver, you can see better that Childe lost his left shoulder (and probably more), so he's about 110% dead. I wanted to make this less obv in the final 🐵
I write and draw my story with many alternatives, and in this one, it was their first and last kiss.
My interpretation of Diluc x Tartaglia is that Diluc knows EXACTLY WHY he loves Tartaglia. He doesn't look at Tartaglia and feels confused, he wouldn't ponder why he is unable to get rid of him.
He will deny his love, but he's not lost in it. He will deny it and pretend theres nothing between them until he can no longer do so. And this is exactly the reason why its so hard for them to get together, but once they do, Diluc turns completely.
This man understands what he signed up for when he decided to love Tartaglia.
Because what makes the fire in Diluc is that he cares. He cares so much and so deeply about so many things. Should he not make the same mistake when he's younger, he has to consider every little thing, always be rational. He has to know the reasons so that he's ready to take the risk.
Tartaglia wanted to fuck but Diluc only want to make love.
