Portal of Evil

Evil forces have been awoken! No one has ever set foot in the dense forest lying to the west of the Cloudhigh Mountains... until now. Gold fever has hit these inhospitable woodlands and the consequences are terrifying! Some deadly, ancient evil has been disturbed and the whole area is suddenly terorized by mysterious prehistoric creatures. It is up to YOU, a renowned and hardy adventurer, to destroy this ancient evil before it's too late. Puffin: #37 1989
