The Murky Hollow is a dark cavern on Port Royal with beautiful waterfalls, and is one of the places where the undead legions of Jolly Roger's army of the undead are spawning from. It is very similar to the Catacombs on Padres Del Fuego. It seems to be an abandoned Naval colony with all the various concrete structures around. The Royal Navy's footmen would have left with the arrival of the Undead into the caves. A pirate can access the Hollow from either Governor's Garden or King's Run.
