June 1798
You are a trusted agent of Grand Master Jean de Valette, in Valletta, Malta, on the eve of the 1565 Ottoman siege.
Your mission: unmask the betrayal threatening to
Delve into the 72 hours that sealed Malta's fate in 1565, a betrayal at the heart of the Great Siege where every decision led to the survival or fall of the Order of Saint John.
« We will fight to the death, and it will be seen if the Turks are braver than Christian knights. »— Jean de Valette, Grand Master of the Order of Saint John, before the Great Siege of Malta, 1565
Valletta, the capital of Malta, was the stage for the Great Siege of 1565, an epic confrontation between the Knights of the Order of Saint John and the Ottoman Empire. Your journey begins in front of Fort Saint-Elmo, a crucial fortress whose fall, after a month of fierce fighting in June 1565, almost annihilated all resistance. It is here that you receive your first instructions, fragments of ancient letters hinting at a traitor among the defenders. The shadow of Dragut, the Ottoman corsair mortally wounded nearby, still hovers over the walls, reinforcing the urgency of your quest to thwart the plot.
Continue to the Upper Barrakka Gardens, from where you'll overlook the Grand Harbour, a privileged access route for enemy fleets. This spot, once an observation post for Italian knights in the 16th century, becomes your point for analyzing suspicious movements. Secret Order archives suggest a Maltese emissary might have met Ottoman agents here, exchanging vital information about the city's defenses. The cannons saluting the sunrise at the Saluting Battery recall the constant vigilance needed during the Siege of Malta.
The Auberge de Castille, an imposing edifice whose construction began after the 1565 siege, served as the headquarters for the knights of Castile, Leon, and Portugal. It was within its walls that crucial strategies and decisions were made. As a spy, you must find a message hidden there by a loyal knight, potentially a double agent, who may have recorded evidence of the betrayal. The architectural details of the Baroque facade, added in the 18th century, might conceal cryptic symbols related to the plot.
St. John's Co-Cathedral, built between 1573 and 1577, stands as a testament to the Knights' victory over the Ottomans. Before its transformation into a Baroque masterpiece, the site was already a place of spiritual gathering. Here, amidst the chapels of the various 'Languages' of the Order, you must decipher a code based on the coats of arms and tombs of the Grand Masters. Caravaggio's allegorical paintings, like The Beheading of Saint John the Baptist, illustrate the violence and sacrifices of the era, resonating with the urgency of your own mission in Valletta.
Your investigation will then lead you to the Grandmaster's Palace, and through Triq ir-Repubblika to City Gate and St James Cavalier. These locations, witnesses to Valletta's evolution since its post-siege founding, hold the final pieces of the puzzle. At the Grandmaster's Palace, the former residence of the Grand Masters, you'll discover how the betrayal almost compromised Jean de Valette's efforts to secure the island. Understanding these events, which led to the construction of this fortified capital, will allow you to grasp the magnitude of the task and the importance of unmasking the traitor, thus ensuring Malta's legacy for centuries to come.
