A One-Round Living Greyhawk Bissel Regional Adventure
From the introduction:
The dark revelers gathered amidst the screams and howls: they plead for death. Two captives are held. Release for them spins out the rescue of the rook. One is the younger of two cruel brothers, a mask of jealousy worn. Darker than that is the other, her secrets are wicked and true things.
A Bissel regional adventure for [character levels] 2 - 12, and Part 3 of the Shadows and Sigils series.
Note: This adventure will be of particular interest to members of the Thieves Guild of Dountham.
