The Realm of Spirits was a location within Zarrak's mountain on the forest moon of Endor. According to the Ewok Zarrak, only the greatest wizards were able to enter and return from its depths. In 3 ABY, Zarrak attempted to plunge the Ewok Teebo into the Realm of Spirits, but he was stopped by the Ewok Shaman Logray. During a fight with the Ewoks, Zarrak was attacked by flying leaves, manipulated by Teebo, causing him to run from the attack and fall headfirst into the Realm of Spirits.
