"You cannot build an empire based on slaughter and deceit. Turhan knew that. I thought you did too."
- – Urza to Londo, 2259
Urza was a member of House Jaddo which was a long time ally of House Mollari. From this alliance, came the childhood friendship of Londo Mollari and himself. Soon they both blossomed into proud and ambitious young Centauri looking to prove themselves to each other and to the world. Sometime in their youths, they participated in the dueling society "Couro Prido" (Proud Knives) to which Urza earned the nickname "Skal Tura" (Silent Beast). During these competitions, Urza always thought that Londo fought like a madman with the Coutari earning him the nickname "Paso Leati," a name that he would refer to him as throughout his life. Londo always fought well but was never really a match for Urza.
Urza joined the military and participated in the Battle of Gorash, a situation that later haunted him and left him disillusioned with military glory, even though he was hailed as a hero. Seemingly afterwards, Urza became a politician attaining the rank of Vocator. He apparently began to agree with the moral scruples of Emperor Turhan that warfare was no way to build or rebuild an empire. This apparently made him powerful enemies in certain political circles, including Lord Refa.
In 2259, a resolution was drafted in the Centaurum by way of Refa that would declare Urza and his entire House traitors to the Republic. He arrived on Babylon 5 to ask for Londo's help, but when he heard of his old friend's connection with Refa he was furious. In a last ditch effort to save his family he challenged Londo to the Morago, a fight to the death, knowing Londo would not face the dishonor of refusing. He maintained the upper hand in the fight, but allowed himself to be killed. In accordance with the rules of Couro Prido, by dying in a duel to a fellow member his family became part of Londo's, sparing them a life of misery and destitution, as no resolution against his family could now harm them.
- Urza's sole appearance was in Knives, though his death would have repercussions for Londo, especially regarding his alliance with Refa.
- Urza's accent (and by extension Londo Mollari, and Antono Refa's) is characteristic of Centauri Prime's northern province and is generally indicative of the "old school" of court nobility.
