Mûl Âon was a cousin of Khamûl of Laeg Góak. After the Hiona had rised against Khamûl's tyranny, they were supported by Númenórean adventurers and elevated Âon as the new Mûl. Khamûl’s dethronement probably saved the Wômaw from the Shadow, as the deposed monarch could do little more than swear a vengeful oath - a curse that he would act upon a millennia later. The wiser Mûl Âon became the ancestor of the later rulers of Wômawas Drûs.
