Valletta — The Grand Masters' Venom

🎭Your Mission

You are a loyal Knight of St.

John, summoned to the shadowed halls of Valletta in the late 18th century. A sinister venom has struck down the Knights Hospitaller's

**Plot and Succession: Thwart Grand Master Perellos's Conspiracy!**

« « It is in the shadows that the most venomous plots are born. » »
An anonymous chronicler of the Order, 1716

Succession intrigues at the heart of the Order

The Order of St. John, though religious and military, was always a hotbed of political intrigue. Composed of 'Langues' (national divisions like France, Aragon, Italy), the election of a new Grand Master was a crucial event, often preceded and followed by intense power struggles. Each Langue sought to place its own candidates or influence the Order's policy in its favor, which could lead to fierce rivalries and plots hidden beneath the veneer of piety and chivalry.

During the reign of the Grand Masters, Malta's stability heavily depended on the personality and capability of the Order's leader. The illness or death of a Grand Master was a period of great vulnerability, where rumors of treason, sedition, or poisoning proliferated. Although often unproven, these rumors reflected a political reality where poison was perceived as a potential weapon in power struggles, exacerbating distrust within the highest echelons of the Order.

1530
Emperor Charles V cedes Malta to the Knights of St. John, marking the beginning of their sovereignty over the archipelago.
1697
Ramon Perellos y Roccaful, knight of the Langue of Aragon, is elected 64th Grand Master of the Order, beginning a 23-year reign.
1720
Death of Grand Master Perellos. Although the official causes were natural, rumors of a prolonged and mysterious illness persist.
