The mission: Your story in Melbourne

A mysterious red diamond has resurfaced in the whispers of Melbourne’s streets. 

As the trusted companion of Nasiha, a woman with hidden motives, you’ll follow cryptic clues, unlock forgotten codes, and chase the trail of a long-lost secret society. 

From the grand halls of Flinders Street to the quiet whispers of Chinatown and the waters of the Ornamental Lake, your mission is clear: recover the diamond before it vanishes again. 

But be warned, every riddle uncovers not only a clue but a question about who Nasiha really is… and why she chose you.
