Judging by published Pathfinder adventures, the draugr may be the most popular monster in the Bestiary 2. This isn’t a surprise. Certain deaths are so horrible that they seem to deserve their own monsters, and death by drowning is clearly one. The nausea-causing draugrs are also an excuse to go whole hog with the gory descriptions. “Their attacks smear rancid flesh, rotting seaweed, and swaths of vermin on whatever they hit,” says the Bestiary 2 (and thanks to the Pirates of the Caribbean series, players have no trouble connecting those dots in their imaginations).
The templars of Dol Imri are known as much for their banking system as for their skill in fighting infidels. When one of the Templar Knights’ lost treasure ships returns as a ghost ship, the sailors and paladins have all become draugrs, while the paladins’ Master is now a draugr captain wreathed in green obscuring mist.
Sages say the plains of the Middle Passage were once a vast inland sea. No human eye witnessed that epoch, but the theory would explain the strange fossil fish sometimes unearthed in farmers’ fields there—as well as the elven draugrs that sometimes erupt from the soil to attack homesteaders, wielding magical harpoons and still rotting of fish despite now being thousands of miles from the water.
Certain dark priests can summon forth draugrs. The rival sects of Urodel, the Marsh Queen, and Hungry Jinn, the spirit of shipwrecks, send draugr minions against each other in their never-ending war of attrition, with poor coastal communities caught in the middle.
