Ser Willem Darry was a knight from House Darry who served as the Red Keep's master-at-arms for King Aerys II Targaryen. He remained deeply loyal to House Targaryen during and after Robert's Rebellion. According to semi-canon sources he was the brother of Ser Jonothor Darry of the Kingsguard.
Appearance and Character
After King Aerys II Targaryen learned of the death of Prince Rhaegar Targaryen at the Trident, the Mad King sent Queen Rhaella Targaryen and Prince Viserys Targaryen to Dragonstone, presumably with Willem. After Aerys's death in the Sack of King's Landing and Rhaella's death during labour, the garrison of Dragonstone considered selling the two Targaryen children, Viserys and the infant Daenerys, to the new king, Robert Baratheon. However, before the garrison could come to a decision and before Stannis Baratheon arrived for his assault on Dragonstone, Willem and four loyal men smuggled Viserys and Daenerys from the island and fled to safety in Braavos.
In Braavos, Willem lived with Viserys and Daenerys in the house with the red door. While in Braavos, Willem was visited by Oberyn Martell and together, with the Sealord of Braavos as witness, they signed a pact promising that Viserys Targaryen would one day wed Arianne Martell in return for the support of Dorne in winning Viserys the Iron Throne. However, Willem took sick when Daenerys was 5 years old (either in 289AC or 290AC and slowly wasted away, dying an unknown amount of time later, leaving the two children to their own devices.
