A Feast for Crows
When Garse's father Garth travels to Oldtown to take ship to King's Landing to serve on the small council as the new master of coin, Garse and his brother Garrett accompany him, as Lord Tywin Lannister had promised to find a place for them. When informing Queen Regent Cersei Lannister about this, Lord Mace Tyrell suggests Garse and his brother are named to the City Watch of King's Landing. However, Cersei, wishing to prevent the presence of another Tyrell on the small council, prevents Garth's promotion by quickly naming Lord Gyles Rosby as the new master of coin.
