Paedrig is one of the Heroes of the Horn.
Paedrig appears when Mat blows the Horn of Valere outside of Falme and participates in the battle against the Seanchan. When Rand looks at the faces of the Heroes, he hears a hundred names to go with them, names that they were known by in other lives. One of the names that he thinks of when he looks at Paedrig is Patrick.
