This adventure can be done as a one shot adventure or it can easily slot into a larger 'Curse of Strahd' campaign.
A Turtle Dragon youngling had been eating all of the fish in Lake Zarovich. Once the food supply had been exhausted it turned its attention to eating people at the lake. This was no surprise to Thalvin, he knows how much food a Dragon Turtle needs to consume every day just to survive. What did surprise Thalvin is this lake is not connected to a sea, and the rivers that do are not large enough for this gargantuan creature. He will task the adventurers to find out where the Dragon Turtle came from.
This mini-suppliment gives the option for players to either start as land based or water based characters and will take them to an underwater village enhabited by Xotls and then onto a sunken temple to investigate where a mysterious Dragon TurtleYoungling came from.
