In the shadowed halls of Valletta, a sinister venom struck down the Knights Hospitaller's Grand Masters one by one
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
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.
