Legend (1985)

In a mystical forest bathed in sunlight, the fate of Creation hangs in the balance. Only when the sinister forces of evil have slain the last unicorn on Earth will the wicked Lord of Darkness have the power to cast the world into an endless night. With his horrible goblins scouring the virgin land to capture the magnificent creatures, it's up to pure-hearted forest dweller Jack and his beloved Princess Lili to undertake an impossible quest. Together, they must defy the abyss and restore harmony to the universe. But as they soon realise, the struggle between light and darkness demands sacrifice. Can two valiant mortals overturn the dark plans and re-establish the eternal balance of the cosmos?
