A One-Round Living Greyhawk Veluna Regional Adventure
From the introduction:
A research expedition to the temple where “Heart’s Lament” was rediscovered has gone missing. The Museum of Mitrik, the College of the Arcane, and House Mori are looking for a few heroic and knowledgeable adventures who are large of heart (but not of size) to find the expedition members and see if there is more to this seemingly simple shrine.
A Veluna regional adventure for character levels 4 to 15.
This is a loose sequel to VEL6-08: Heart's Lament that is not terribly centaur-friendly.
Players that have not played VEL6-08: Heart's Lament should not play this adventure, as spoilers are inevitable.
