The Palacio de la Lamentable Muerte is a lost palace, buried deep under Raven's Cove.
It is said that thousands of years ago, the evil Witch King had ruled Raven's Cove with an iron fist, but eventually met his downfall at the dawn of civillization. His fortress was buried deep under Raven's Cove. Only recently have explorers dug a tunnel that lead deep down to the fortress. However, explorers soon discovered that the Witch King's rule had not ever come to an end, and found that the once fallen king had returned in Undead form and had began to raise an army to retake Raven's Cove, and then the Caribbean.
