Gateway to the Savage Frontier (1991)

As the story opens, you and your companions are celebrating in triumph. The caravan you've been guarding has just completed its dangerous passage to the trading town of Yartar. But the realms are full of danger and there is tension in the air. Great armies are on the move, and the relative peace of recent times will soon be shattered. Your party becomes a problem to the evil forces whose plans lie behind the current troubles. Only by the swiftness of your sword--on land and water--will you live to save the region from certain destruction.
