Stories of the city and tales of fabulous artifacts originating from Carsall still abound. Now, the clerics of a seaside town have proven that some unusual items are indeed from the legendary city--and two priests involved in the process, as well as a mysterious stranger, are missing. Are player characters willing to risk life and breath beneath the water to find the lost city? Does the city truly exist, or is the story simply a hoax put forth by crooked fishermen? Take the plunge--explore The Murky Deep!
