I didn’t look back. I ran harder. Fen moved through the growth like he was part of it, ducking branches without looking and stepping across roots without slowing. I was getting better at following him, though not perfectly. Kael kept pace behind me, breathing hard as the silver worked through him. Every few minutes, I heard him stumble and catch himself, and each time, I had to fight the urge to slow down. The bond was gone; I’d severed it and felt it snap. Breaking a bond like ours, the one that ties two spirits together, alpha to mate, wolf to wolf, was supposed to free me, to untangle that deep, instinctive pull we shared. But the habit of caring about him hadn’t faded yet. “Almost there,” Fen said. “You keep saying that.” “I keep meaning it.” Then the trees opened up, and I stopped. The Hollow wasn’t what I expected. I’d pictured something gloomy, like the rest of the Growth, full of rot, murk, and things with strange eyes. But this was different. The trees here were old, older than anything I’d seen, with trunks as wide as houses and roots rising from the ground in arches tall enough to walk under. In the center was a pool, still and black, perfectly round, as if someone had pressed a coin into the earth. The air shivered with a faint hum, so low I felt it more than heard it, vibrating somewhere in my bones. The silence had a weight to it, deep and steady, pierced only by an almost imperceptible ringing in my ears, like standing close to something ancient and vast. The smell was sharp and metal-edged, as if the hollow itself were breathing slowly, watching us. “Don’t touch the water,” Fen said immediately. “What does it do?” “Shows you things.” “What kind of things?” “The kind you can’t forget.” He turned to face me, and his expression was different here. Quieter. It seemed like the Hollow affected him too. The air here pressed against our skin, damp and almost humming, as if something beneath the earth was awake and listening. I could taste metal on my tongue, and my heartbeat felt strangely out of sync for a moment, slower and deeper. Fen’s voice was softer than usual, shaped by the weight in this place. “This is where I came when I went inside the Void. This is where the silver started.” I looked at the pool. My reflection looked back, and even in the darkness, I could see my eyes. They were glowing. Faint, silver-edged, steady. I didn’t know they did that. “Fen,” I said quietly. “What exactly is a sovereign?" He was quiet for a moment. Behind us, Kael lowered himself against one of the great roots, exhausted, watching us both. “You know how Alphas are born into power?” Fen said. "How do the bloodlines carry it forward, generation to generation, predictably and manageably?" “Yes.” “A sovereign isn’t born. They’re chosen by something older than bloodlines. The packs don’t have a word for it anymore because they stopped believing. They burned the records, killed the last ones they found, and rewrote the history.” He paused. “But whatever does the choosing doesn’t care about the pack.” Kael spoke from behind us. His sound was quiet. Rough. Like he was saying something he’d been told never to say out loud. “The actual moon. Not the ritual. Not the ceremony. The thing the rituals were built to imitate.” He looked at me. “My father knows. That’s why he’s coming. He’s known since the Hall.” I turned to look at him. “He knew before the Hall?” Kael’s jaw tightened. “There were signs when we were kids. He told me to stay away from you. I thought it was because you were human.” He paused. “That wasn’t the reason.” The torches on the ridge had stopped moving. That was worse. “They’ve set a perimeter,” Fen said. “They’re not coming in. They’re waiting for us to leave.” He looked at me. “The Great Alpha won’t enter the Hollow. There’s too much old magic here. But he’ll wait us out if he has to. He’s patient. That’s his worst quality at the pool. At my own shining eyes staring back. “How do I end this?” I asked. “Not run from it. End it.” Fen and Kael looked at each other. Something passed between them, not trust, not even close, but a grudging acknowledgment that they were facing the same problem. "You have to challenge him," Kael responded. A formal sovereign's claim. In front of witnesses, under the moon." He paused. "Nobody’s done it in three hundred years." His voice was quieter when he went on. "The ritual… it's not a single fight. There are vows, first blood drawn, and the old words. The challenger and the reigning Alpha stand inside the circle, and every pack member present is bound to witness. If you win, you don’t just take the title, you take on every burden of it. If you lose, you lose everything. The loser forfeits their claim and their life, and their allies stand judged. There’s no mercy in it. The moon decides." He looked at me as if weighing whether to say more. "And if the Sovereign fails, the bloodline is ended, all ties broken. The old stories say the Hollow itself remembers if you run from what’s demanded." “What happened the last time someone did?” Neither of them answered. Which was an answer. I looked back at the pool. The reflection looked back. Calm. Silver-eyed. Waiting. “Okay,” I said. “Okay?” Fen repeated. “Tell me how it works.”
