"Huh?" Marvin gasped for air, clearly having trouble accepting Tom's random announcement. "What do you mean, another world?" he asked, proving that he didn't really digest what Tom told about a moment earlier.
"Like I said," Tom rolled his eyes, "the dungeon doesn't end at its lowest floor. Once you deal with the last boss, instead of facing a wall or secret treasure, you are going to start climbing it... down," Tom said, taking a moment to seat himself in one of the few surviving chairs.
"And once you reach the highest floor again?" Marvin asked, unwilling to accept any default gaps in the story.
"You enter another world," Tom confirmed the truth with a nod of his head.
"And you want our entire family to migrate there, right?" Marvin asked, slowly realizing that Tom wasn't describing a new idea for a fantasy novel but what he actually saw with his very own eyes.
