IV Anbus was a planet, the spiritual capital of Buddislam. Its main city was Darits.

During the Butlerian Jihad, Omnius decided to attack the Unallied Planets before the final strike against the League of Nobles. In 177 BG Omnius forces were detected at the Unallied Planet by the Jihadis and they moved to protect against the assault.

Since the inhabitants were reluctant to help, Xavier Harkonnen was forced to repel the machines by destroying the dam. A huge mass of water engulfed the machines as well as part of the capital along with holy relics and people who refused to leave.
