A wrecker is a person who takes valuables from a shipwreck. Some wreckers deliberately cause shipwrecks.
A wildling woman pulled some scarlet silk from Asshai from a wrecked cog which had washed up on the Frozen Shore. Her granddaughter later used the silk to mend Mance Rayder's torn up cloak after he was attacked by a shadowcat.
Lord Godric Borrell caused shipwrecks by turning off the Night Lamp, a lighthouse. Because the Three Sisters have long tolerated smugglers, Lord Stannis Baratheon, master of ships for King Robert I Baratheon, once sent a fleet to Sisterton and made Godric hang a dozen friends. Stannis threatened to hang Godric as well, should another ship sink because the Night Lamp had gone black.
- Lord Godric Borrell
The lords of the Three Sisters had a black repute, and none more so than Godric Borrell, Lord of Sweetsister, Shield of Sisterton, Master of Breakwater Castle, and Keeper of the Night Lamp… but even robber lords and wreckers were bound by the ancient laws of hospitality.
