Moonlighter is set in the village of Rynoka, which was created when several mysterious door were found to lead to unique places filled with artifacts. The people has started calling these places Dungeon and started venturing into them to gather resources to sell. There are 2 type of people who explore these dungeons, heroes who explore the dungeons and kill monsters for fame and glory, and merchants, people who explore the dungeons in search for artifacts within chests to sell. Heroes are held in greater esteem than merchants as merchants are seen as people who only care about money.
Each dungeon contains a mini boss at each floor, along with a dungeon guardian at the final level. When the dungeons were first discovered, Rynoka was filled with travelers and warriors looking to explore these places, and was very prosperous in the beginning. However, as the casualty rate within the dungeon became too high, the town started closing down the dungeons in order to protect the citizens. This would lead to Rynoka decline because they rely on the artifacts collected from the dungeons. As of now, only 1 dungeon remains open for people to explore.
