Ben was always intrigued by myths and legends, and the tale of the Monsters confined to Mt. Ebott had long captivated his imagination. Rumors whispered that the Monsters were not creatures of this world, but extraterrestrial beings, falsely labeled as monsters and incarcerated on the mountain. The lure of uncovering the truth of this mystery had enticed Ben to embark on a perilous climb up the famed peak.

As he trekked along the mountain's ridge, a curious sense of apprehension and anticipation surged through him. In his hand, he clutched a parchment handed to him by the Plumbers to aid him in his investigation.

He examined the sheet, hoping to glean some insights about the predicament that lay ahead.

Suddenly, his foot caught on a root, and he stumbled forward, unable to stabilize himself in time. As he careened down an abyss, he frantically attempted to activate the Omnitrix to save himself, but the device began malfunctioning, and he tumbled into the hole. A blood-curdling shriek escaped his lips as he plummeted towards the ground, and then darkness consumed him.

When Ben regained consciousness, he lay sprawled on a cold bed of withered yellow flowers in an obscure subterranean chamber. With a sharp intake of breath, he sat up, feeling an aching pain coursing through his body, and surveyed his surroundings. It dawned on him then that he was no longer on Mt. Ebott but somehow transported to the underground realm where the Monsters were exiled.

"What the... Where am I?" he muttered, his voice echoing into the abyss.
