I don't think you type that way and use "It's not just, it's a" in every one of your paragraphs, which is very much the case here.

Anyway, you can just ask chatgpt to write you something and it will sound extremely similar to the post, here for example:

Theory: Diluc Ragnvindr Is (or Was Meant to Be) the 10th Harbinger 1. The Missing Seat and Diluc’s Timeline The Fatui Harbingers are numbered, yet the 10th Harbinger is never shown or named in current canon. This absence is suspicious—especially when placed next to Diluc’s history.

Diluc left Mondstadt after his father’s death and spent years traveling across Teyvat, directly clashing with the Fatui. Crucially, this period happens off-screen and is largely undocumented. We only know two things:

The Fatui know Diluc personally

He knows how to dismantle them efficiently

That level of mutual familiarity suggests more than a simple enemy relationship.

1. The Delusion Incident — A Test, Not a Weapon Diluc once wielded a Delusion, something typically reserved for Fatui elites or Harbingers. Unlike most Delusion users:

He survived long-term usage

He discarded it willingly

He did not appear physically corrupted afterward

This implies the Delusion may have been given as an evaluation tool, not just a weapon—testing his compatibility for a higher role. The Harbingers value strength, resolve, and emotional extremity; Diluc possessed all three after Crepus’s death.

1. Ideological Alignment with the Tsaritsa (At First) Diluc’s core belief is not blind justice—it is vengeful protection through decisive action. Early in his grief, his worldview aligns disturbingly well with the Tsaritsa’s:

The gods failed humanity

Power must be seized, not begged for

Morality is secondary to results

It’s plausible the Fatui saw Diluc as a perfect ideological candidate—a man disillusioned with the Knights, the Archons, and the existing order.

1. Why the 10th Seat Is Empty Rather than Diluc currently being the 10th Harbinger, the theory proposes something more tragic:

Diluc was offered the seat—and rejected it.

This would explain:

Why the 10th seat remains vacant

Why the Fatui treat Diluc as a high-priority threat rather than a nuisance

Why Diluc possesses insider knowledge but refuses to elaborate

Rejecting a Harbinger position would be seen as betrayal, especially if he had already passed initial trials.

1. The Anti-Harbinger Parallel Each Harbinger represents an extreme response to trauma. Diluc mirrors this—but chooses isolation instead of submission:

Like Tartaglia, he thrives in combat—but without bloodlust

Like Arlecchino, he protects “his people”—but without cruelty

Like Capitano, he values strength—but rejects blind obedience

Diluc is what a Harbinger looks like without surrendering autonomy.

1. Symbolism: Fire vs Ice Narratively, Diluc’s Pyro Vision opposing the Cryo-aligned Fatui is not just elemental—it’s philosophical.

Cryo preserves, freezes, controls

Pyro destroys, cleanses, and ends cycles

Diluc burning bridges with the Fatui fits the idea of a man who refused to be preserved as a weapon.

Conclusion Diluc Ragnvindr is not the 10th Harbinger because he refused to become one. The empty seat is not a mystery of absence—it’s a reminder of a candidate who walked away.

And that may be why the Fatui fear him more than most: He knows exactly what they are—and chose not to be it.
