Dahlgur Oasis

"Brast, one of the historians of my order once came here. He called it a 'fertile valley of slender trees and bold flowers. A place where evil has not found root.'"

- Kormac

Dahlgur Oasis is located in Kehjistan.

Lore
The oasis apparently existed before the Mage Clan Wars, over 1500 years prior to the End of Days. According to Eirena, the oasis of this era was much larger than the current version.

According to Abd al-Hazir, in the tenth century, Caldeum depended on small wells for its water. Then came the mysterious Dahlgur, who offered Caldeum an oasis of unparalleled splendor located in an area previously thought to be desert, asking only that his name be permanently affixed to the land. Then, he vanished into the wastes. Aqueducts were constructed, giving Caldeum a supply of water. In 1285, thanks to The Nephalem, the oasis was again able to provide Caldeum with food and water.

In-game
The oasis is visited in Act II of Diablo III.

Somewhere in the Dahlgur Oasis, the unique Dune Dervish, Sokahr the Keywarden, can be found. Sokahr drops the Key of Hate (Key of Gluttony), necessary for the Infernal Machine event.
