Fighting Fantasy - The Port of Peril - Rules of Play says:
In this brand new addition to the multi-million-copy-selling Fighting Fantasy series, you - the hero - must travel all over Allansia - from old haunts Darkwood Forest to Port Blacksand - on a dangerous quest. What starts as a treasure hunt soon takes a darker turn, with the potential return of the most terrifying foe of the original books, Zanbar Bone, on the increasingly dark horizon.
