As Katreina had said, the sea was wide and all-reaching. It consumed everything.
About seventy percent of this planet's surface was covered by oceans. Sirens were the most low keyed, friendly and pacifist species, but also the ruler of the largest piece of real estate on this planet. They lived under the sea for over ten thousand years, during which the continents experienced changes in the multitudes, endured weathers of all kinds, and were reigned by dynasty after dynasty — including "Gods". In the past ten thousand years, civilizations had rise and fallen repeatedly, leaving behind various artifacts that found their way to the ocean, and ultimate into the sirens' collection.
