From publisher blurb: Doom Down Below! Merlin summons the party to his tower for a dire task—find where important figures from across the globe have gone and free them from captivity. Of course once the adventurers discover what's really going on it's a whole lot bigger of a problem than some kingly kidnappings and missing empresses. Indeed the entire world will be affected by what the PCs learn about beneath the waves! What's inside Epic Depths: A subterranean and underwater adventure for characters of 21st level. Statistics for the joristenz and porosi monsters, as well as the dreaded Marwolaeth. Beautiful isometric cartography by Tommi Salama. Pregenerated adventurers of 21st level for every class.
