A One-Round Living Greyhawk Regional Adventure set in the Duchy of Urnst
From the introduction:
Peace is a delicate and easily shattered thing. Peace between ancient enemies is even more delicate and should be appreciated for ever existing, not for how long it lasts. The peace between the Duchy and Rary seems to have its heart in the right place, but it has been said that it is doomed to fail. Rumors of dervishes raiding into the Abbor-Alz seem to verify this, but the only people hurt by it will be the settlers and tribesmen there. Can you help them?
A one-round regional adventure set in the Duchy of Urnst for characters level 4-14.
