Plot

The game takes place in the fictional land named Yuria. a high fantasy world in the style of Conan the Barbarian.

An evil entity known as Death Adder captured the king and his daughter, keeping them both captive inside his castle. Death Adder also finds the Golden Axe, which is Yuria's symbol, and with it, he threatens to destroy both the ax and the royal family unless Yuria's people accept him as their ruler.

So, three warriors set out on a mission to save Yuria and avenge their losses at the hands of Death Adder. The first is Gilius Thunderhead, from the Wolud mines, who had his twin brother murdered by Death Adder's soldiers. The second is the barbarian Ax Battler, who seeks revenge for the murder of his mother. And last but not least, we have Tyris Flare, who had her parents murdered by Death Adder himself.

The warriors rescued the inhabitants of the then-plundered Turtle Village, named after the shell of a giant turtle. This turtle takes the heroes across the sea and then flies to Death Adder's castle on the back of a giant eagle. Once at the castle, the heroes defeat Death Adder, who was taking over the Golden Ax, and save Yuria.

In the PC and Mega Drive versions, the heroes fight Death Adder's mentor, the Death Bringer, as the true final boss. After the battle, they receive the Golden Ax and are blessed with immortality.
