Base (Great Pyramid)
The base of the Great Pyramid is at ground level.
The base is a hushed place, full of dust and shadows. Within the ground level walls, sounds echo off arches of many coloured brick, and amongst the stables, stalls, and storerooms.
A Dance with Dragons
When conspiring to arrest Hizdahr zo Loraq, Barristan Selmy and Skahaz mo Kandaq have a secret meeting by the stables. Missandei had transferred the message between them. The location had been chosen because the stables are always quiet after sunset. While there, Ser Barristan notes to himself that the silver and the elephants are at their proper places.
