Exploration Society Letters

Quest Overview
"We have contacted residents of six cities located in Osteth. These residents have agreed to don the green cap and robes of the Agents of the Society. They have hidden their official town stamp in dungeons near each of their towns. Find the Town Stamp and use it on your Red or Gold Letter. This will create a Stamped Red or Gold Letter, marked with the name of the town whose stamp you used. Take this Stamped Letter to one of the Agents and exchange it for a reward."
