Ser Warrick Manderly was a knight from House Manderly during the reign of King Aegon I Targaryen.
Since the Three Sisters had declared Marla Sunderland their queen during Aegon's Conquest, King Aegon I Targaryen tasked Lord Torrhen Stark, his new Warden of the North, with ending the rebellion. Torrhen granted command of a northern army to Warrick, who sailed from White Harbor to the Bite on Braavosi galleys. The Sistermen's Rebellion ended when Sisterton spotted Warrick's fleet and Queen Visenya Targaryen on her dragon, Vhagar. Marla's younger brother, Steffon, became the new Lord of the Three Sisters and sent one of his sons to be fostered by the Manderlys at White Harbor for his good behavior.
