Ashaba was a location in in the Karand kingdom of Katakor. The castle there, also known as the house of Torak, was where Torak lived after stealing the Orb of Aldur from Aldur, and prior to having it stolen from him by Belgarath the sorcerer.
After the theft of the Orb Torak was so furious that he destroyed Ashaba. Many years later it was destroyed even further by the demon lord Nahaz.
Torak's time at Ashaba is notable because it was then that he was overcome by prophetic madness and penned the Ashabine Oracles.
