Pherro Oordar was a politician, Jeen of Ernele, the youngest son of Kren, brother of Kren the Younger and uncle to Hee and Iar, founders of Tref.

Kren the Younger wanted Pherro to succeed him as head of the clan. Some time in 1591 or 1592 Pherro was captured by Hee and Iar and was used as a bargaining chip in negotiations between the brothers and the rest of the family. Kren the Younger agreed to exchange Pherro for the city of Orden. This, however, triggered Nilma Oordar to challenge his leadership and Kren the Younger was murdered as a result. Nilma installed his son Rodare as head of the family. This forced Pherro to switch sides and join Hee and Iar instead.

Pherro hoped to become head of the clan by helping Hee, since he was older and believed that by challenging the legitimacy of Rodare he would be able to make a case for himself and have Hee support him.
