Arah

Arah was once home to the gods while they shaped the world of Tyria. It was maintained for many years by the Forgotten and then later by Humans in the form of the Empire of Orr. When Orr was destroyed by The Cataclysm, Arah sank to the ocean floor along with the rest of the empire.

Trivia
After the defeat of the Great Destroyer, Livia claims she is going to set off to Arah. In the cutscene prior, she is seen about to grasp the Scepter of Orr.
