In the books
In the A Song of Ice and Fire novels, Ser Oswell Whent was a younger brother of Lord Whent, known and remembered for his dark humor. He wore a distinctive helmet emblazoned with a black bat with its wings spread, symbolizing House Whent. Oswell was present at the Tourney at Harrenhal where Jaime Lannister became a Kingsguard. In the books, Ser Oswell was present with Ser Gerold Hightower and Ser Arthur Dayne in the Showdown at the Tower of Joy with Lord Eddard Stark. After Ser Gerold tells Ned they were not at the Battle of the Trident, Ser Oswell declares, "Woe to the Usurper if we had been." He and his two brothers are slain along with the bulk of Ned's force in the ensuing melee, the only survivors being Howland Reed and Ned himself.
