|The Mystery Knight (appears)
Lord Shawney supported Daemon I Blackfyre during his rebellion in 196 AC. He fought in the Battle of the Redgrass Field where he was on the right of the Blackfyre host, under the command of Bittersteel. He was wounded during the battle and almost died but ultimately survived. He was pardoned by King Daeron.
In 212 AC, Lord Shawney came with his retinue to Whitewalls to attend the wedding of Lord Ambrose Butterwell and his second wife, Lady Frey. On his way, Lord Shawney had to cross the God's Eye via a ferry. He quarrelled with Lord Costayne on the matter of which lord should cross first; Shawney argued that as the older of the two he should go first, whereas Costayne believed that as his House was nobler then Shawney's, he had the precedence.
During the wedding feast, Lord Shawney was seated on the dais. The next day, he attend the wedding tourney and bet on Ser Duncan the Tall to win (five to one) against Ser Uthor Underleaf in the joust.
