House Tirado is one of the known Noble Houses of Tear.
The only known member of the house is Lady Yseidre Tirado, who was a noblewoman of the province of Tear during the days of Artur Hawkwing's Empire. After the High King's death in FY 994, Lady Yseidre formed an alliance with Lord Istaban Novares and seized control of the city and the surrounding countryside. With neither being powerful enough to become king or queen of the nation, they formed a ruling council, which developed into the High Nobility of Tear during the War of the Hundred Years.
As House Tirado has not been mentioned in the events around 998 NE, it may be extinct.
