Urhi Shalma - sometimes spelled Uhuri - from Red River is Queen Nakia's personal servant, an assassin who usually takes the guise of a royal priest.
He takes advantage of his position and his uncommonly feminine appearance to gain the trust of people to be used in Nakia's plots against Yuri and Prince Kail. His surname is not well known, and is used when he chooses to go incognito. Under his robes, he hides a number of whipping scars. In Volume 11, he loses an eye to Rusafa and wears an ornate eyepatch for most of the rest of the series.
A former member of a royal family, Urhi's nation was invaded and destroyed when he was a young boy. Taken captive by the invading nation's commander, he was savagely beaten (leaving the scars on his back), raped and later castrated to ensure that his family's bloodline would not continue. He arrived in Hattusa after being purchased to serve as a priest in the seraglio temple.
Urhi is initially rumored to be the true father of Prince Juda; this is proven false when his castration is revealed. However, he and Nakia did share a strong romantic interest in each other.
