Erol Otus' Map in White Plume Mountain

Is so evocative, so accessible, so ready for any fantasy hungry GM to put his stamp on it that I have to make my attempt. I feel like my three characters from fantasy campaign #1 are suited for the role. The campaign ideas I sketched out in the initial post are essentially story hooks seeking to set the party onto adventuring. A straight forward quest. I need only to shoe horn this intriguing destination into the campaign setting suggested by the three starting characters.
