Since this time, however, Ovarion had sat empty, as following the taboo after additive modifications are made to the landscape by the Changer. As the songs taught: On grounds newly laid, one must wait for the Dweller to enter the Palace. This dictum served a both potentiating mystical reflection on intent and purpose and an utterly practical use: in case the Changer should reappear and happen to change his mind, and reclaim what had been called forth. The songs told it had happened before, but not in recent living memory.
