A one-shot 5e adventure set on the high seas. This adventure can be played stand-alone or dropped into any campaign. It's ideal for those occasions when your player's characters need to take an ocean voyage.
Your player's characters are not the only passengers on the ship. A group of priests are escorting the bodies of their fallen brethren back to their temple to be buried. Little do your characters know that these are evil priests and the coffins in the cargo hold do not contain dead bodies but horrible undead.
The pleasant sea voyage turns ugly when the evil priests and their undead minions attack.
