Tim didn't have many thoughts on what the afterlife would bring, he had never really thought about it. Maybe he'd go to heaven or hell, or be reincarnated, or maybe he would even go to Valhalla. But when he saw the oddly bright mushroom rise from behind the city skyline, he definitely didn't expect to wake up as a orb of space in the middle of absolutely who knows where. Not being able to understand the senses of literal stone and air, definitely wasn't helpful. Note that this isn't the typical dungeon core story. The way dungeons work, and how they interact with the people around them is unique. There are no system screens or stats that allow something to happen because "magic". Instead there's magic with a few simple rules, more science than anything really, which allow those with the know-how and imagination to accomplish great things.
