It was a fairly small desert.
It was situated between several sand dunes of varying sizes. It slept deeply under the gloomy sky, and everything in it was dead silent.
Then, the sand on the ground began to tremble slightly.
*Thump!*
There was a dull thud, and an uneven platform suddenly rose in the middle of the desert.
*Thud!*
More dull thuds followed. Countless grains of sand gradually fell from the rising platform and into the dark hole beneath it. The falling sand hissed.
The platform was about several meters wide. It kept rising and revealed its black-gray surface.
More than ten seconds later, a figure covered in dust and sand emerged from the dark, mysterious hole with a torch in hand. The figure patted the sand off himself and glanced around.
