The House of the Undying is a grey and ancient ruin. It is long and low, without towers or windows, and is coiled through a grove of black-barked trees with inky blue leaves which are used to make the drink that the Qartheen call, "shade of the evening." Black tiles are on the roof, many of them fallen or broken. The mortar between stones is dry and crumbling (II: 508)
It is said that many people enter the Palace of Dust, but few come out (II: 508)
A person who would seek audience with the Undying Ones must enter their House alone or not at all (II: 509)

There are all manners and styles of rooms and furnishings inside the House of the Undying (II: 510)
The chamber of the Undying is gloomy. A long stone table fills the room, above which floats a heart swollen and blue with corruption. It beats with a deep throbbing sound and each pulse sends out indigo light (II: 514)
Around the table are figures. They speak with voices that are part whisper and part moan, some male and some female (and one seems to speak with the sound of a child) (II: 514)
It is difficult to summon the will to speak in the chamber of the Undying (II: 514)
