It was believed that the first inhabitants of Dilgul were the ancient Arhûnerim before they split into multiple branches that later differentiated them. The ancient Ulgath had baptized the city and given it that it's name because of the rocky natural bay that formed in the cliffs. It was an arid and rugged area and one could access the sea only through a small pebble beach and a tunnel through the cliffs barely big enough to let pass a small boat, that led to the center of the bay. In the core of the bay a big rock hid the entrance to the tunnel and the city stood hidden behind the cliffs. It had long been a fishing settlement of the Donath during the second Age, until they were pressed westwards by Ulgathic tribes .
