Prologue

This is a modern world where everything was peaceful but one day for unknown reasons dungeons started appearing in this world and from those dungeons monsters started appearing too.

Each dungeon had a different treasure based on the difficulty level. So the higher the difficulty level of the dungeon the better the treasures you'll find. Due to this many guilds were formed all around the world.

Many years have passed and people got used to life as if the dungeons and monsters were nothing new but something they've always known.

One day at midnight a dungeon appeared just like any other dungeon in a country called "Luciana".

[Author Notes: Luciana means light or shinning]

This dungeon was unlike any other. It was the biggest dungeon the world has ever seen, which would later be known as "The Great Dungeon". Seeing how big it was the country of Luciana alone couldn't raid the dungeon even with all its guilds joining together. Many other countries wanted to join the raid in these dungeons since there can legendary treasures waiting to be found there.

Since everyone wanted to join this raid. The country of Luciana decided to make this a joined operation with the rest of the world with certain rules that no guilds can fight each other over the treasures and no matter what the treasure is the country of Luciana will keep 30% of it from everyone.
