The Ruins of Arkkoran are what remain of a once large ancient night elven temple known as the Temple of Arkkoran. It was the home of the sea giant Arkkoroc.
The temple was completely destroyed by either the Cataclysm or the newcomer Bilgewater goblins, leaving no trace of the building but just the ruins that once surrounded it on the shores of Azshara.
