The last dinosaur's muscles tensed as he drew in a deep breath, his powerful chest expanding. With a sudden, thunderous force, he unleashed a roar that shook the very air—a primal challenge that had once sent prey scattering in terror. The sound echoed across the wasteland, rattling the metal structure before him.

The mechanical hum stuttered for a moment, then grew louder, more insistent. A seam appeared along the structure's surface, splitting open with a hiss of pressurized air. Inside, dim blue lights pulsed in rhythmic patterns, illuminating a narrow corridor that led deeper into the unknown. A strange, synthetic scent wafted out—something sterile and alien.

The dinosaur hesitated, his instincts warring between curiosity and caution. His nostrils flared as he took a step closer, his claws clicking against the metal ramp that extended from the opening. The interior seemed to breathe, the walls shifting subtly as if alive. Whatever awaited him inside was not of this world—but it was the first sign of anything beyond solitude he had encountered in decades.

A low, modulated voice suddenly emanated from within, speaking in a language he did not understand. Yet, beneath the foreign syllables, there was something almost... familiar. Like the ghost of a memory from a time before the world died.
