Aerorn

Mythical City, its name means holy city in elvish, though ancient translations suggest a connection to the sea or even a mystical sea tree.
"Aearon," a term bearing striking resemblance, signifies the vastness of the ocean.
Legend has it that this fabled city may have once stood within the enigmatic Sundered Sea, witnessing the cataclysmic event known as the Sundering, which spelled the demise of both the elves and the ancient metropolis.
Whispers persist of elven refugees fleeing to the realm of the Feywild, some managing to escape before the city's ruin befell them.
Rumors abound that Aerorn was perched upon the crescent-shaped Isle, only to succumb to the depths, swallowed by the unforgiving waters.
