The Story

Far-off from any trade routes, in the middle of the ocean, lies a small Island named “Isstic”. While many know its approximate location, nobody has claimed to have set a foot on it. Deadly currents, sharp cliffs and a constantly brewing storm make the island practically inaccessible for ships. Normally, the name of the island would’ve been long forgotten by history. However, most scholars know that Isstic was once home to a great trading empire. Under King Chorn the Cunning, the empire started to regulate and tax the spice trade from the west and the raw materials trade from the east. Through this, Isstic rose quickly to great wealth and considerable power, without producing many goods of their own. Then, around 300 hundred years ago, every mention of the great empire of Isstic and its royal family simple vanished from the records of the time. Yet, the island is still there in the great Sea – as if it is waiting for a new conqueror.

In this 4 – 6-hour adventure, a party of 4th to 5th level characters find themselves stranded on the island of Isstic. Searching for a way off the Island, they’ll have to forage through the ruins of a once great civilisation. The Island may seem friendly at first, but one warning is repeated all over the island: “Be Seen By Nobody!”

Notes for the GM / DM

  • This adventure will require some time to set up an intrigue. If your players are slow in fights or aren’t used to finding creative solutions to a problem, the module might take longer than 6 hours to run.

  • The rule-set for fighting the giant monster of the module is just a suggestion. Experienced DMs may use it as a base to adjust it to their campaigns needs.

  • If you have a party member that can fly, this adventure module will be hard to run. Either find an excuse we that PC can’t fly or don’t run this module.

  • The final fight isn’t meant to be resolved in a normal battle. The GM might have to fudge the numbers a bit to create a thrilling chase instead of a static battle.
