Summary
“Why are you so desperate to get under my skin?”
Agatha shrugged nonchalantly even though her heart was pounding. “You’ve lived comfortably enough in that palace of yours. I’d like to bring you back to reality.”

“Again, you don’t know what you’re talking about.”

Summary
“I did not enter this marriage under grounds of love or other frivolous feelings,” Rio said, voice steady. “It was an act of duty. Nothing more.”
Agatha tilted her head, folding her arms.
“You paid quite a high price for ‘nothing more’, Your Majesty.”Rio’s jaw twitched. Her eyes sharpened — dangerous controlled. But cracking.
Agatha felt it. The shift, the restraint, the want.
She wanted to break it.
She wanted to own it.OR
With the king dead and the kingdom on the brink, Princess Agatha is placed on the auction block — a pawn to be bartered for power, her hand sold to the highest bidder.
She expects a life of misery. Obedience. Silence.
She does not expect Rio Vidal. The cold, revered queen of a neighbouring realm. A warrior cloaked in shadows and secrets. A woman who seems determined to keep her at arm’s length.
Their marriage is a weapon. A wall. A vow.
But no walls are strong enough to stop what is destined to grow between them.

Summary
“What do you want to do?” Rio started. “And I don’t mean us, I mean you.”
Agatha stared at her for so long that the silence felt like a threat, like carbon monoxide, slowly but surely suffocating whilst you’re none the wiser.
“Aggs-”
“I want to leave.”
Maybe Rio’s heart stopped. Maybe the world had ended. Maybe her ears were deceiving her.
“You…say that again.”
Agatha dropped her head. “I want to leave Barcelona, Rio.”

Summary
Teen sits down next to her. “Do you wanna talk about it?”
Agatha very much does not.
How exactly would she even start, anyway?
Just ‘oh yeah Rio and I used to be in a super secret sexy Jedi marriage and then our child died and we haven’t seen each other until the other night when she tried to take my head off with an Inquisitor’s lightsaber but I brought her here to help with this job even though I’m not sure I ever really know who she was if she’s willing to work for the Empire now but I’m doing it anyway because I’ve spent years in the furthest parts of the galaxy trying to forget her and now that we are on the same planet I can’t keep away for another second’?
Yeah, that would go over great.

the Star Wars AU where Agatha and Rio are Jedi, and then Order 66 happens and things fall apart.
