Belgrade, June 8, 1922. King Alexander I Karadjordjević is marrying Princess Maria of Romania. The royal wedding is the grandest event of the decade, a symbol of unity for the newly formed Yugoslavia. However, beneath the grandeur of the celebration, powerful forces are at work.

This is a world unlike the one you know. In this alternate history, Nikola Tesla never returned to the USA. Instead, he helped electrify Serbia and fueled an industrial revolution, leading to a more advanced and prosperous nation. Through smart diplomacy and the influence of political forces, Serbia avoided the Balkan Wars and even World War I, yet still managed to unite the South Slavs peacefully, forming Yugoslavia. Tesla’s innovations are everywhere, from the electric trams to the palace’s cutting-edge security systems, making this world one of rapid progress and hidden dangers.

You have been summoned to the opulent estate of Nikodije Maric, a shadowy figure with immense influence. Though you’ve never met him, each of you owes him a favor for past help, given when you needed it most. Now, Nikodije calls upon you to repay that debt.

With the royal wedding approaching, he speaks of a threat hidden beneath the surface of the celebrations—something that could jeopardize the future of Yugoslavia. Nikodije’s knowledge is incomplete, but he is certain that a great danger lurks within the palace. He entrusts you with the task of infiltrating the wedding, investigating the palace, and neutralizing the threat before it can do harm.

Obviously, this one is for mature audiences only, since it deals with Lovecraftian Cosmic horror themes. Character sheets are prepared and ready, and the system itself is intuitive to understand, so begginers are welcome.
