The library echoed with the guttural growl that ripped from the doorway. The hulking figure, bathed in an ominous shadow cast by the full moon filtering through the window, towered over the stunned group. Its eyes, glowing an unnatural crimson, locked onto Ethan with a predatory gleam.Claire's blood ran cold. This wasn't Ethan. This beast, its matted fur the colour of midnight and its claws dripping a viscous black liquid, was far more ferocious, more monstrous than anything she'd ever imagined.Ethan, drained from the ritual that shattered the crystal and seemingly freed him from the curse, sank to his knees, clutching his stomach. Fear contorted his face, not for himself, but for Claire."Who… who are you?" the Sheriff stammered, his hand instinctively reaching for the gun holstered at his hip.A chilling chuckle echoed through the room. The creature, its voice a raspy growl barely decipherable, spoke. "Think of me as the true inheritor of the curse. A shadow Ethan inadvertently set free with his little ritual."Realization dawned on Claire. The forgotten passage in the book – the sacrifice wasn't Ethan's humanity, but the curse itself. And by shattering the crystal under the full moon, Ethan had unwittingly released another entity trapped within it – a more ancient, a more powerful werewolf.Panic clawed at Claire's throat. The Sheriff and his officers, mere mortals against such a beast, were frozen in fear. Ethan, weakened, lay vulnerable on the floor. It was up to her.But how? The crystal – their only hope – lay in shattered pieces on the floor. There was no time for despair, no room for fear. Thinking back to the book, she remembered a passage about moonlight channelling energy.Desperate, Claire grabbed a shard of the crystal, its edges sharp and cold against her skin. Focusing on the moonlight streaming through the window, she held the shard aloft, channelling all her will into it.A faint glow emanated from the shard, a mere ember compared to the full power of the crystal. But it was enough. The beast, sensing the lingering lunar energy, let out a deafening roar and lunged towards Claire.Time seemed to slow down. Claire, with a desperate cry, thrust the shard towards the creature's glowing red eyes. A blinding flash erupted from the shard, momentarily engulfing everything in its brilliance.When the light faded, the library was silent. The beast was gone, vanished without a trace. Ethan lay unconscious on the floor, his chest rising and falling with shallow breaths. The Sheriff and the officers, still shaken, stared at Claire with a mix of awe and confusion.Relief flooded Claire. She had stopped the creature, but at what cost? Was the curse truly gone, or had it simply transferred to another, perhaps an even more dangerous host? Ethan's future hung in the balance, shrouded in a new layer of uncertainty.As the first rays of dawn painted the sky a pale pink, casting long shadows through the library windows, the authorities took Ethan into custody. Claire, exhausted and emotionally drained, watched them go.The sacrifice had been made, but the victory tasted hollow. The unanswered questions hung heavy in the air – the fate of the curse, the identity of the new werewolf, and the future that awaited them all under the light of the next full moon. The battle was far from over. The whispers in the library had only just begun.
