Unfortunately the surrounding world is not always as friendly. There are many caves throughout the world that are normally used for exploring and adventure. In the past few months, evil monsters have started coming up from the caves and attacking the citizens.
The King has come to you for help. Recently the King's rare stamp collection was stolen. He believes the sudden increase in the monster population and his missing stamps are no coincidence. The King tells you to start exploring the cave right next to the town to start looking for clues as to where his precious stamps are.
On a side note, all of the King's daughters are missing. He thinks some may have been kidnapped, some might be lost, while others may have just run away. He will reward you greatly if you can return all the princesses back to the castle.
