The Biasire, Carchemish's grim stronghold of captivity, looms with an imposing austerity. Encased within thick, rugged limestone walls, the prison's architecture is stark and utilitarian, dominated by massive stone blocks and harsh, unyielding lines. Its towers are squat and formidable, standing watch like vigilant sentries, while narrow slits serve as windows, barely permitting light to penetrate the dim interior. Iron grates guard each entry, tarnished by time and reinforced against any breach. The inner chambers are cold, echoing with the distant clang of chains and low murmurs of the imprisoned.
