A One-Round Living Greyhawk Veluna Regional Adventure

The life of an adventurer is one of constant conflict... of the soul within as well as with adversaries without. The characters will contend with both, and face the consequences of each, in an effort to ensure that vanquished threat to Veluna remains so.
A one-round Regional adventure set in Veluna for characters level 4 - 14, wherein PCs may forward the cause of good or commit themselves entirely to evil.
