This is the limited edition module aimed at characters of 4th-6th level produced exclusively for Gen Con Indy 2003, and is currently out of print.
Publisher's blurb: "A terrible storm forces the players to take refuge in a lighthouse that warns travellers of a nearby moor. But what appears at a first glance to be a safe haven is in fact a trap set by the malevolent ghost of a long-dead troll. Can the players find and slay the ghost troll. Or will they be trapped forever in the haunted lighthouse."
