The Wailing Caves is a zone within Freeport's Commonlands. The caverns and dark pits are carved out of limestone and hold the secrets of the orc raiders. The Wailing Caves may be found by heading westward from the Smuggler's Path through Dead Man's Valley. The only entrance is marked by a huge snarling stone face that's carved into the side of a mountain. The Caves consist of a complex system of locked and hidden rooms, and a deep pit with a spiral ramp.
The orc raiders perished long ago. They were once known as the Raiders of the Shin'Ree. Once powerful, they are now tormented souls in skeletal form living within an underground fortress. The Raiders of Ree are currently attempting to reestablish their hold on the Commonlands region.
Upon entering the Wailing Caves, you'll meet a gnome looking for your assistance. Beyond him, you'll encounter the remains of those who perished in these dark caverns. Once past them, you will come face to face with the forces of the growing Ree empire and perhaps some of their allies. After dealing with them, you'll have to make your way past the powerful Advisor, who holds a key to the lower chambers that eventually lead to a final mysterious locked door.
