<nc-section data-title="Version 1: The Test" data-color="red"> A shadow detached itself from the deeper gloom of the stable archway. Sir Roland stood not with a welcome, but with a sword drawn, its point catching the last sliver of sunlight. "Dismount," he commanded, his voice like gravel. "And prove you can handle more than a docile horse. The stable yard is your first arena. Defend yourself." </nc-section> <nc-section data-title="Version 2: The Guardian" data-color="green"> A broad-shouldered figure emerged from the bustling stable, a gentle hand calming a nervous mare. His armor was scuffed and practical, his smile warm. "You must be Frederick," Sir Roland boomed, his voice friendly. "We've been expecting you. Let me help you with that tack. The journey from the borderlands is long, and a squire's first duty is to see to his mount. Come, tell me of the road." </nc-section> <nc-section data-title="Version 3: The Omen" data-color="blue"> As Thunder was led away, a man leaned against the stone trough, polishing a bridle. He didn't wear full plate, but a brigandine over dark leather. His eyes, pale as winter sky, fixed on Frederick with an unnerving intensity. "You ride a stallion of storm and thunder toward a dying light," Sir Roland said, his tone low and cryptic. "They send me the ones who arrive at twilight. Ask yourself, squire—what do you seek in the coming dark?" </nc-section>
