Together or individually, you all are answering a call for help. The high priest of Kelemvor, Doomguide Yovir Glandon, of the city of Phlan has requested able bodied adventurers to look into attacks on small coastal communities in the area.
Magiries, the request for aid came to you directly. Given your history with Enar you invited her along, two holy warriors being better than one after all. The rest of you were called in more general ways, but the feeling you got was that this isn't a trumpet call for any and all to answer. This call is more targeted, it seems that Doomguide Glandon doesn't want to incite panic.
You've made your way to Phlan on the passenger ship Paulina, and any who have mingled with the crew have heard rumors that the attacks have been from a pirate ship. There are even quieter rumors among the passengers that it is some sort of "ghost ship", but the crew refuses to discuss the subject out of superstition. If there is some sort of ghost pirate ship out there, they don't want to tempt fate by discussing it.
Paulina has just tied up at the dock and disembarkation has begun. You know that Doomguide Glandon can be found at Valhingen Graveyard and that he wants to discuss with you in person just what his concerns are.
