Accursed Dungeon

In a place that exists neither here nor there, exists a Dungeon. This place has no entrance and it's unknown if it even has an exit. Such a place likes a certain type of person, one of little importance, one who is likely not to be very missed. People who are talented, ones who have a role in the world aren't likely to be chosen, if at all. After endless cycles of summoning countless victims each perishing faster than the last, as is their fate, another person had been chosen and summoned forth to explore the Dungeon.
