House Jordayne of the Tor is a Dornish noble house. Their seat is placed on the coast of the Dornish Sea. George R.R. Martin confirmed that the house is a homage to Robert Jordan. The lord is called “Trebor” which is “Robert” backwards “Jordayne” is similar to “Jordan” and “Tor” is Jordan’s publisher.
