From A Wiki of Ice and Fire
Piety is a war galley in service to pious Lord Guncer Sunglass.
A Clash of Kings
Piety is seized by Stannis Baratheon when Lord Guncer Sunglass refuses to acknowledge Stannis as his liege, since Stannis destroyed the sept at Dragonstone. It is part of the fleet commanded by Ser Imry Florent during the Battle of the Blackwater. During the battle Piety is engulfed and destroyed by wildfire after the explosion of the Swordfish.
