A Storm of Swords
Deziel is one of the Dornish nobles who are part of the entourage of Prince Oberyn Martell when he comes to King's Landing to claim the seat Tyrion Lannister had offered the Prince of Dorne, Doran Martell.
A Feast for Crows
While imprisoned by her father, Doran, Princess Arianne Martell considers contacting Deziel for aid. She decides against it, however, considering him too dutiful to his liege lord to be willing to act against him, and not nearly powerful enough to be successful.
