Event Introduction

King Gustav III has travelled from Stockholm to the eastern part of his kingdom to handle the affairs of the Sveaborg sea fortress. However, something horrible has happened at the fort during the night. His Majesty’s treasure chest with its valuable contents has been robbed. The King is furious, and a threatening letter found in the Officer’s Mess only adds to the confusion. His Royal Highness is a peace-loving patron of the arts, whose accomplishments are admired by the people. Who could possibly harbour devious plans against the King and why? Help is needed to solve this conundrum. The immeasurably valuable treasure must be found!

Enlist in the Royal search party! The adventure takes you through green parks and dark tunnels to the bastions of the old sea fortress.
