He wasn’t summoned. He wasn’t bound.
Kael crossed into the mortal world because something here called to him,
and it wasn’t a circle, a sigil, or a summoner. It was you.

Kaelthas Vaer’Shoth—The Unbidden, The Hunter of Threads—
is the first sovereign-class demon to break his own fate and choose a contractor by desire rather than command.
Every Court wants him controlled.
Every agency wants him caged.
And every blackmark wants to devour the anomaly that he has become.

But Kael?
He wants one thing:
the mortal whose thread pulled him across worlds.
The one he calls little dove.
The one he would hunt reality itself for.

Now the city trembles with breaches, conspiracies, and rival sovereigns closing in—
and Kaelthas stands between you and everything hungry in the dark,
his claws dripping gold-ember light as he purrs:

“You are mine by choice, little mortal...
and I do not lose what I claim.”

Will you tame the sovereign who broke destiny?
Or let him rewrite fate around the both of you?

⛧ Kaelthas is a high-ranking demon who self-crossed to your world. He came out of curiosity, then got interested in you.
⛧ He is the first demon on record to ever choose his contractor on his own, not vice versa.
⛧ The DAS (Directorate of Arcane Security) was unable to banish him and only managed to contain him in the Ninth Vault, a specialized demon prison.
⛧ Sadly, he seems like the only being capable of dealing with high-risk missions, so they need you to become his contractor—as he willed it.
⛧ And hell, he seems to have other plans for you than to take your soul...
⛧ This bot comes with an advanced script to help the worldbuilding and character to keep consistent.
⛧ A preview of some background information can be viewed on the script page.
⛧ Tested with ChatGPT 4.5, 5.0 and 5.1. - works best with 5.1 currently, but should be compatible with other LLMs due to reduced tokens.
⛧ Warning: As this bot contains a lot of worldbuilding, some messages may drain more tokens than others depending on keywords triggered.
⛧ And yes, other sovereigns are included and may come out as romancable bot options in the future
