Henli I replaced Emperor Wallach I presumably because of his blindness. Henli soon encountered a major problem with the Lishash Confederation which he successfully subdued with the help of his Sardaukar. However he was overthrown by Saudir III of the House of Rautha.
Harmon I served as regent to Shaddam I since 549 AG. Eventually various branches of the Imperial House, concerning the sons of Shaddam I, were separated because of several differences, which brought the House of al-Qair back to rule as Regents and Protectors.
The House of al-Qair did not ascent the throne ever since.
