Tholindis Explained: The Forgotten Genius Behind Genshin Impact’s Greatest Tragedy

Deep within Genshin Impact‘s Song of the Welkin Moon Archon Quest lies one of Teyvat’s most heartbreaking stories—the tale of Tholindis, a brilliant researcher whose love and sacrifice shaped the destiny of Khaenri’ah and the Five Sinners. Appearing in Rerir’s memories during Act IV “An Elegy for Faded Moonlight,” this Crimson Moon descendant’s research on Moon Marrow opened portals between worlds and inadvertently created one of the most devastating villains in Genshin lore.

Tholindis at a Glance

The Hidden Descendant: Tholindis’ Dangerous Heritage

Crimson Moon Dynasty Explained

Before King Irmin’s Eclipse Dynasty ruled Khaenri’ah, the Crimson Moon Dynasty held power. When Irmin seized control, he systematically hunted descendants of the previous royal line, viewing them as existential threats to his throne.

Tholindis’ Unique Position:

• Distant descendant (not direct lineage)
• Lacked X-shaped pupils of direct descendants
• Successfully hid heritage from everyone except her university mentor
• Pursued academics over family connections

Physical Distinction: Unlike direct descendants such as Arlecchino and Orlog who possess distinctive X-shaped eyes marking their bloodline, Tholindis appeared normal—a genetic quirk that saved her life but couldn’t save her heart.

Life at Universitas Magistrorum

Tholindis enrolled in Khaenri’ah’s national university, specifically the Moon Marrow Laboratory. This prestigious institution became her sanctuary from family expectations and royal persecution.

Academic Focus: Rather than politics or power, Tholindis dedicated herself to solving Khaenri’ah’s energy crisis through alternative sources—a noble goal that King Irmin’s Abyssal obsession would ultimately undermine.

Groundbreaking Research: Moon Marrow’s True Nature

What Is Moon Marrow?

Moon Marrow represents fragment-like material originating from the Crimson Moon’s collapse—a catastrophic event in Teyvat’s ancient history.

The Discovery That Changed Everything

Tholindis discovered Moon Marrow behaves as a spatial gateway to another world—revolutionary technology that could transport people between dimensions or locations. However, she couldn’t determine:

• The exact process for controlled travel
• The destination world’s location or nature
• How to reverse or track portal journeys

Resource Starvation: King Irmin’s obsessive focus on Abyssal energy research redirected all funding and personnel away from Tholindis’ work. She continued alone, conducting experiments with minimal support, driven by the belief her discoveries could save Khaenri’ah from the king’s dangerous path.

Preserving the Legacy

Recognizing King Irmin’s growing instability and fearing Khaenri’ah’s imminent collapse, Tholindis entrusted Moon Marrow samples to another descendant named Frithr. This desperate act ensured the Crimson Moon bloodline would survive beyond Khaenri’ah’s destruction.

Modern Connection: That preserved legacy flows through Arlecchino (Peruere), who received the Iridescent Moon’s Marrow from Columbina in Act III. Tholindis’ 500-year-old research continues shaping present-day Teyvat.

The Love Story: Secrets and Sacrifice

Two Hearts, Two Lies

Tholindis and Rerir’s relationship thrived on genuine affection but crumbled under hidden truths:

What Tholindis Hid: Her Crimson Moon heritage and King Irmin’s hunt for her people What Rerir Hid: His role as the king’s enforcer, killing Crimson Moon descendants

The Proposal: Despite their secrets, Rerir proposed marriage. Tholindis didn’t immediately answer but was certain of their future together—a tragic irony given what awaited them.

The Unbearable Truth

When Tholindis discovered Rerir was responsible for her people’s deaths—executing King Irmin’s orders to eliminate Crimson Moon descendants—she faced an impossible moral dilemma. Rather than hatred, she felt:

• Understanding of his difficult position
• Fear for her own survival
• Love that refused to die despite everything

Her Response: Tholindis secretly helped survivors escape while maintaining her relationship with Rerir, carrying the weight of knowing her beloved was her people’s executioner.

The Portal’s Final Use

During the Abyssal monsters’ invasion of Universitas Magistrorum, Rerir rushed to save Tholindis. He found her standing before her completed portal—the culmination of years of research.

Tholindis’ Final Words: She revealed knowing his secret all along and claimed the portal was her “solution” to free him from his burden. Stepping through, she believed she was giving Rerir the normal life he desperately wanted.

Rerir’s Devastation: Her disappearance shattered him completely. Consumed by grief and guilt, he embraced Abyssal corruption, transforming into the Rächer of Solnari—one of the Five Sinners. He created another portal pursuing her but has searched 500+ years without success.
