Undertale

Legends say that many years ago, humans and monsters fought one another. After a long war, the monsters were sealed deep underground. Years have passed. At the summit of a fog-shrouded mountain, a human appears. Curiosity takes hold, and the next step proves fatal. The ground gives way beneath your feet.

After a long fall, there is a sensation of a soft landing. Instead of jagged rocks, you find yourself resting on a bed of golden flowers. It is quiet all around. Above, only a tiny sliver of light is visible—the path back is far too high.

Where... am I?

Ahead, an ancient stone doorway looms. Beyond it lies the unknown. From the darkness, a small figure with a golden face and a kind smile emerges.

— Hello. Welcome to the Underground.

The stranger watches you intently, waiting for a response.
