Pyat Pree is a warlock from Qarth and also a member of the Thirteen.
Pyat Pree is one of the alleged warlocks of Qarth, a wise man who claims mystical powers. Together with the rest of his order, he dwells in the mysterious House of the Undying, located within the city of Qarth. Even though the power of and respect for the warlocks has considerably waned over years and many dismiss them as little more than charlatans performing parlor tricks, tradition and custom has allowed Pyat Pree a place among the Thirteen.
Pyat Pree is present when the Thirteen greet Daenerys Targaryen at the gates of Qarth, and she and her people are allowed into the city.
Pyat Pree attends a reception for Daenerys in the gardens of the home of Xaro Xhoan Daxos. He personally welcomes Daenerys Targaryen on behalf of the Warlocks of Qarth. He gives her a gem and tells her to look into it until she can see herself in its facets. When she looks up Daenerys sees that there are now two of him talking to her. He invites her to come the House of the Undying. Xaro apologizes for the warlock, he says that though they are not thought highly of, it is customary to extend the warlocks an invitation. Ser Jorah Mormont gets a warning from the mysterious woman Quaithe to beware that all men will wish to see the dragons, and in seeing them, will lust after them.
Daenerys's dragons are stolen from Xaro's home. Xaro uses the theft as a pretense to hold a council of the Thirteen in his home. He then stages a coup with the assistance of Pyat Pree and declares himself King of Qarth. The warlock uses his magic to kill the rest of the Thirteen. They reveal that they stole the dragons and have taken them to the House of the Undying. Daenerys flees in terror. Pyat Pree stops her in the entrance hall using another of his duplicates. He tells her to come to the House of the Undying to be reunited with her children. Ser Jorah arrives and stabs him in the back; the body disappears, and only the clothes remain. Another double reappears next to the window, again asking Daenerys why she resists.
When Daenerys travels to the House of the Undying to retrieve her dragons, Pyat Pree creates illusions around her as she travels throughout the House's chambers. When she reaches the room with her dragons, Pyat confronts her, saying that his magic was reborn when the dragons were born, that it is strongest in their presence, and that the dragons are strongest in hers. Using magic, he chains Daenerys, telling her she will stay with him for an eternity to fuel his magic; however, as he does this, he inadvertently provokes the dragons. Upon her saying dracarys, the dragons open fire on him, roasting him alive in seconds.
The warlocks of Qarth try and get revenge on Daenerys by sending an unidentified warlock to Astapor to assassinate her. The knight Ser Barristan Selmy saves Daenerys, however, the warlock escapes using magic.
A warlock of Qarth, Pyat Pree is a member of the Thirtenn who met Daenerys outside of the walls of the city. He colluded with Xaro Xhoan Daxos to imprison Daenerys and steal her dragons, but he was killed when Daenerys commanded the dragons to burn him.
