The old master thief had had the huge, circular edifice built some fifty years ago, just before the final, impossible theft that had made his reputation forever. Then he had retreated into it with his prize, the jewel called the Eye of Abarraden, thumbing his nose at the entire city. Since then many thieves had tried to track the old master to his lair to obtain his secrets, but the Maze had defeated them all.
– Jame's narration, Blood and Ivory: A Tapestry, "Bones"
As a landed master, Penari got the Temple District. For his manor, he hired the architect Rugen to build the Maze, a replica of the city of Tai-tastigon itself as it was at the time.
Around 2969(see calculations) Penari stole the Eye of Abarraden, and he became known as "the greatest thief in the history of Tai-tastigon." After that, he effectively retired and disappeared into the Maze, rarely leaving it.
Theocandi was jealous of his older brother's reputation as the city's greatest thief. Theocandi became a great thief himself, eventually becoming sirdan of the guild. Penari was not jealous of Theocandi in return, much to Theocandi's anger.
For decades, Penari refused to take any apprentices, as the whole guild coveted his secrets and any apprentice he took would be driven to share them. As an old man, he finally did take one apprentice, Jame: A Kencyr who could be guaranteed to keep his secrets.

↑ 2.02.1God Stalk, Book I: Tatters of Dusk, "Chapter 2: The House of Luck-Bringers" — " 'Why, the greatest thief in the history of Tai-tastigon, which is as much as to say in the world, and the only man ever to know all the streets of the city. […] For fifty-six years, ever since that man stole the Eye of Abarraden under circumstances that weren't just difficult, mind you, but physically impossible, every thief in the guild has dreamed of becoming his apprentice.' "
↑God Stalk, Book III: Shroud of Days, "Chapter 13: Three Pyres" — "For the most part, he lived quite comfortably with his memories and the supplies left weekly by arrangement inside one of the Maze entrances, only emerging himself on special occasions, such as the time Monster had chosen the previous Feast of Dead Gods to come down with a sore throat, which required physic."
↑God Stalk, Book II: Crown of Nights, "Chapter 5: Winter Days" — "the life-long rivalry between the Sirdan and her new master. Theocandi had always been jealous of Penari's reputation and raged at his older brother's refusal to envy him his own position and power."
↑God Stalk, Book I: Tatters of Dusk, "Chapter 4: The Heart of the Maze" — "It was obvious now why Penari had chosen her, a Kencyr, to be his apprentice. After decades of pressure to make him reveal his secrets, he had taken revenge on them all by choosing to confide not only in an outsider but in one whose very race was to him a guarantee of her incorruptibility."
