Bring Undelivered Mail to Town Crier

Obtaining either a Undelivered Letter, Undelivered Package the first time, will give you this quest. Once completed, you can return either one of these items to a Town Crier in an NPC town 3 more times, to collect a set of the magic prints.
 * After receiving a full set of these magic prints, you can still return these items for a reward of gold and xp.

Trivia
Town Criers will now pay you for retrieving undelivered mail found in adventure scenes. This has a chance to offer players a bonus reward from a set of four prints of elemental magic (earth, air, fire, and water).
