Zelda II: The Adventure of Link

The Adventure of Link takes place several years after The Legend of Zelda. An older, taller and perhaps wiser Link has seen the country prosper and villages spring up. But peace is a fragile commodity in Hyrule and history has a way of repeating itself. On his second adventure, Link becomes a master of magic as well as a fighter. He visits many towns, fights new enemies and travels across the sea.
Marked by the sign on his hand, Link was destined to become a hero, but in the peaceful days following his first quest, he became restless. He wandered the forests, crossed the deserts and delved into the caverns of Hyrule, looking for clues to explain his feelings of unease. In time he became aware of a wisper that passed between the birds, beasts, and even through the blades of grass: there was a new magic in the land, nameless and terrifying.
Lying as still as a marble, Princess Zelda slept the dreamless sleep of enchantment. When Link found her thus arrayed in the North Palace, he saw at once that she was spellbound. His greatest fear had come to pass. By refusing to reveal the secret power of the Triforce to a wizard, Zelda had brought on her own downfall. But all was not lost. If Link somehow unlocked the mystery of the Great Palace, he could save Zelda and the Triforce of Courage.
