The Sunken Maw

Publisher's blurb:

This ruined ship graveyard rests on the bottom of the ocean, overgrown with coral and other strange underwater plants.

With this map and its system-agnostic one-shot adventure featuring undead pirates seeking treasure which will grant them immortality, you’ll save so much time as you prepare for a fun session. The battlemap comes ready for both VTTs and easy home (or professional) printing—so you can use it no matter how you prefer to run your sessions!
