Welcome to the world's largest casino.
About
Walden, a giant city in the western part of the continent. Once a glamorous imperial capital where royalty and nobility resided, the city fell into ruin after decades of war. At its heart lies the old royal palace, half-destroyed by the fighting. However, a wealthy man purchased the palace and transformed the building into a massive gambling hall.
That is the Grand Casino Nocturna.
