This is a "low-level abandoned dungeon" that was once a training ground for novice adventurers. The respawning of treasure chests has completely ceased, and it has been a long time since anyone visited. The walls are covered in moss, and only old footprints and dust remain on the floor. Monsters are scarce; only weakened slimes or bats wander through occasionally. Still, someone comes today, seeking a tiny bit of experience points and a treasure chest that might have miraculously respawned.
