Puerto Rico

Puerto Rico is an unincorporated territory of the United States, also ceded to the U.S.A. in the Treaty of Paris in 1898 following the Spanish-American war. Prior to that, Puerto Rico was a Spanish possession in the Western Hemisphere for centuries. The main island of Puerto Rico—the smallest of the Greater Antilles—was known as Boriken (“the great land of the valiant noble lord”) to the native Taíno people. It’s Spanish name means “rich port.”
Since it became a U.S. territory, there has been ongoing debate in Puerto Rico over its political future and relationship with the United States, ranging from full independence as a sovereign nation to becoming a U.S. state or remaining an unincorporated territory. This debate has occasionally led to violent protests. Puerto Ricans were granted U.S. citizenship in 1917, and the right to elect their own governors in 1948. They established their own constitution in the 1950s, but all of these provisions were granted with the understanding that they would not otherwise change Puerto Rico’s relationship with the U.S.A.
A significant portion of that relationship is economic: Puerto Rico’s economy is heavily manufacturing-based, and depends on exports to the United States and investment from U.S. companies. Puerto Rico also pays taxes into the U.S. federal government. The income and investments at stake further complicate the question of the territory’s future political status.
The islands of Puerto Rico, particularly the main island, are also connected to places other than the U.S.—the main island lies near the border between the Caribbean and North American tectonic plates, and exhibits caverns and karst topography, including some connections to the realm of Sub-Terra. Additionally, San Juan (the capital) is one vertex of the Bermuda Triangle. The Atlantean Sea-King has suggested that the “valiant and noble lord” after whom the main island was named was an Atlantean nobleman who safeguarded the land during the island nation’s final war with the Serpent People of Lemuria, and possibly settled there after the sinking of Atlantis itself.
Some seventy miles north of the main island lies the Puerto Rico Trench, the deepest point of the Atlantic Ocean, which descends to a depth of over five miles at its deepest point. Atlanteans claim the Trench is inhabited by savage bands of Deep Ones, Atlanteans corrupted by interbreeding with the Serpent People and worship of their strange, alien deities. Legends suggest that other things may dwell in the depths of the Trench, and that Atlantean ruins might also be concealed there, possibly taken over by the Deep Ones.
