Ser Gywin Lannister

The Castellan of House Dae, and twin brother of Lady Dae.

Bio
A son of a least branch of House Lannister, he swore his sword to the service of House Dae when his sister, Lady Dae (then Lady Anna Lannister) married Lord Sebastion Dae. He distinguished himself by rallying House Dae's forces when House Faust and their vassals marched on Dawn's Reach and killed Lord Dae. Afterwards, Ser Gywin was given command of a large portion of House Dae's forces to march south and retake Castle Silford. Gywin's forces arrived and put the castle to siege, waiting until House Clairvale's forces could march on Castle Silford from the south. Together, the two small armies stormed the castle, slaying most of its occupiers and freeing Lord Daniel Silford and what remained of his men.
