The last dinosaur moved with slow precision, his nostrils flaring as he took in the metallic scent of the strange structure. It smelled foreign—sharp and unnatural, like nothing he had encountered before. His muscles tensed, ready to spring at the first sign of movement. As he drew closer, the hum grew louder, vibrating through the ground and into his bones.

He circled the structure, his sharp eyes noting the way the metal seemed untouched by time or weather, unlike the ruins of the old world he had seen before. There were no seams, no visible doors—just smooth, unbroken surfaces that reflected his own weathered form back at him. The symbols etched into the sides pulsed faintly, as if alive.

A sudden hiss made him recoil. A small panel slid open near the base, revealing a dark interior. The hum shifted in pitch, almost... inviting. The dinosaur's instincts warred within him—curiosity against caution. The last time he had encountered something unknown, it had cost his kind everything. But what else did he have to lose?
