Smoke was already rising from the settlement by the time they crested the final ridge, though not the wide, unrestrained columns of the pass camp fire. Smaller. Contained. Almost deliberate.
"She's not burning the settlement," K said, reading it the way Zayn read terrain. "She's burning something specific."
They rode in cautiously, weapons ready, but the chaos Sofia had expected wasn't waiting for them. Instead, the settlement's residents stood in loose clusters throughout the main paths, watching a single building burn at the center of town, the same modest building where Sofia had first met K and Lira less than two hours earlier.
Lira's fighters were gone.
"Where is everyone," Sofia asked a woman standing nearby, watching the fire with an expression somewhere between shock and relief.
"They left," the woman said. "Right after you did. Loaded up wagons that had apparently been packed for days, and rode east, torching the meeting hall behind them." She looked at K with something wary in her expression now, the careful trust the settlement had extended their co-leader clearly shaken. "They took the archive with them. Everything Lira had written. Everything about the philosophy, the histories, all of it."
K's face went through several expressions in quick succession, relief, fury, something that looked almost like grief.
"She's not finished," K said, quiet. "She just decided this settlement wasn't useful to her plan anymore, now that her cover's blown. She's rebuilding somewhere else, somewhere I won't be able to warn people about, with everything she needs to start over."
Sofia dismounted, watching the meeting hall burn, the fire finally beginning to die down as the settlement's people worked to contain it before it spread further.
"What happens to the Unbound now," Sofia asked.
"I don't know," K admitted. "Half of what I believed, I still believe. The power you carry is dangerous, Sofia. That part was never a lie, whatever Lira's actual motives turned out to be underneath it." She watched the last of the flames gutter out. "But I also just watched someone I trusted with two years of my life use my search for a sister as bait, and burn down the thing we built together the moment it stopped being useful to her. That changes how I hold the rest of it."
Sera approached, having quietly organized the two scouts to help the settlement's people with the fire, her expression carrying the particular exhaustion of someone who had expected a diplomatic meeting and gotten a battle instead.
"We should return to the palace," Sera said. "Zayn's deadline is tomorrow. If we're not back, or if word doesn't reach him, he rides east with whatever force he can raise, and that complicates everything, especially with Lira's people scattered and unpredictable now."
Sofia nodded, though something in her resisted the idea of leaving so quickly, the settlement's people still working to salvage what remained of the burned hall, K standing amid the wreckage of everything she'd spent years building.
"Come with us," Sofia said to K. "To the palace. Not as a prisoner, not as a political statement. As my sister, if you're willing to try being that, even provisionally."
K studied her for a long moment, the offer clearly unexpected.
"I don't know if I can be what you're hoping for," K said. "I still believe most of what I told you in that room. The power frightens me. It should frighten you too, if you're being honest with yourself."
"It does," Sofia said. "It always has. That's not disqualifying. That's just honest." She held out her hand, the same gesture Sera had offered at the crossroads. "Come see how we've actually built the system you doubted exists. Watch it, question it, tell me every place you think it's failing. I'd rather have you inside that conversation, pushing back, than out here building a movement someone like Lira can hijack the moment it's useful to her."
K looked at the offered hand, then at the settlement around her, the people who'd trusted her leadership now uncertain, the archive stolen, the philosophy she'd built her identity around suddenly tangled up with a dead man's daughter and a plan Sofia had nearly died walking into.
"I'll come," K said finally. "Not because I've changed my mind about the danger. Because I watched what happens when someone builds a movement around an idea without anyone close enough to question their methods, and I don't intend to be that person, even by accident, ever again."
They rode west together as the sun began its descent, six riders became seven, the settlement receding behind them, still smoking faintly at its center, and Sofia felt the ring from Isolde's bundle in her pocket, no longer cold, warmed now by hours of carrying it, no longer just a symbol of a sister she'd never met but a girl riding beside her, uncertain, wary, but present.
Two days later, they reached the palace gates exactly as Zayn's deadline arrived, and Sofia watched him come through the courtyard at a near run, the careful architecture of his composure cracking entirely at the sight of her, alive, and the unfamiliar woman riding beside her.
"You're late by an hour," he said, pulling her into an embrace that spoke far louder than the words themselves.
"We had a complication," Sofia said, muffled against his shoulder. "I'll explain everything. But Zayn, first. This is K. My sister." She pulled back enough to see his face. "And somewhere east of here, Voss's daughter just burned down her own movement's headquarters and disappeared with an archive full of everything her father ever wrote about ending our bloodline."
Zayn's eyes moved past her to K, cataloguing, assessing, the strategist rising even through the relief of Sofia's return, and behind him, in the courtyard, Sofia saw Elda go very still at the mention of Voss's daughter, her face carrying the specific dread of someone who had feared exactly this outcome and hoped, quietly, to be wrong.
