Nasaton was the siren's city, which was hidden in the middle of the Pacific Ocean. It had existed since the dawn of time and the city's glorious days were even before the Mythological Age on land. Aside from the sirens, no one knew how to get into the city. Not the technologically-advanced humans, or the omnipotent supernatural gods of yore. None had managed to locate Nasaton. Some had theorized that the city was located deep in one of the ocean's trenches and it was obscured by volcanic activities deep under water. Some had argued that a massive invisible barrier was erected to prevent unwanted guests from poking their heads in. However, all these guesses were quite far off the mark.
