"[meeting in the Great Shaft] Rehgahro Tiwah. The Great Shaft. Amazing, is it not? Built by those from beneath - my people. I am D'ni. It was this shaft that permitted the great-grandmother of Yeesha to find our deep city. Rather than bore you with tedious details, you need only know this: She killed us all, and the great D'ni city lies lifeless and ruined. There is a room at the end of this first elevator, a small room with a D'ni rest Age Book, for the D'ni who would have travelled this path. The Book will link you to Direbo. I will come to you there."
