This is not the Earth that you and I know. This Earth is in an alternate reality, where different rules apply. Most of the events that happened on our Earth happened on this Earth as well, though caused by different things. You see, this Earth has levels, magic and dungeons. Adventuring into these dungeons is a way of life for a lot of people. Jonathan just turned 18, which means he is eligible to become an adventurer. Follow Jonathan and his friends as they begin their journey.
