Prome Ou is the leader of the Ou family and something akin to a spiritual leader for the Silver Tribe. Prome Ou's resposibilities include being the vessel for the Silver Tribe's darker nature, as the Silver Tribe believes emotions to be useless, and also the ability to absorb the fear and anger that any Silver Tribe member may develop.

She also possesses the ability to hold ancient memories and share them with others. She demonstrates this ability when she shares the memory of the Golden Tribe's homeworld with Dhianeila.

As the war between the the Silver and Iron Tribes intensifies, Prome Ou becomes the chief proponent of the peace faction within the Silver Tribe.
