A One-Round Adaptable Living Greyhawk Adventure
From the introduction:
Merchants have been coming up missing. Rumors abound of vampire and devils; others say that a murderous minion of Ivid V or Iuz is trying to make a name for itself by squeezing the lifeblood from the city. Will adventurers succeed, when city authorities only seem to bumble? The first part of the Legacy of Ill-Drach.
An adaptable adventure for characters level 3 - 8.
A separate, brief DOC supplement was provided to adapt this module to Sunndi regional play.
