From publisher blurb:
The Blood Sea is a deadly place, between the monsters, the pirates, and the corruption oozing out of buried Kadum's flesh. In Blood Sea Rising, characters rescue a contact from a pirate crew and take their first steps on a journey that will bring them into conflict with all of the horrors the Blood Sea has to offer.
Blood Sea Rising can be played as a one-shot adventure for first level characters to introduce players to this area of Ghelspad, or can form the first part of a much longer campaign: sequels will be coming to the Slarecian Vault throughout summer and fall 2019.
While this adventure stands alone, future sequels will require the use of the excellent [Blood Sea: Crimson Tides] by Celeste Conowitch. This book provides rich lore and new player options for DMs and players alike, so is a great read in its own right.
