You need time off. Whether you narrowly escaped with your life from a group of cultists summoning a demon, a pirate attack, or anything else dangerous, you have ended up on the resort island of Rela. Here, sunny beaches and warm weather greet you. Hopefully, you can forget about the danger, but as you prepare to relax, you hear news of the guests going missing. While you could maybe disregard this rumor when the resort offers a big reward for anyone to find and stop the cause of the disappearances, you cannot just ignore it. It's time to get back to work.
This is a 2-3 hour one shot adventure balanced around five level 4 characters. Will the heroes be able to overcome the evil within the Crystal Grotto or will they become the next victims?
