During the last quest, Princess Rose reclaimed the powerful Dreamstone, but a new enemy lurks on the horizon, vowing to destroy her and her loyal companions.

With Loken the shape-shifting Sprite taken hostage, the entire realm is threatened with total destruction. A perilous mission to save him and to capture a deadly necromancer plunges Rose and her comrades into dangers they could never imagine.

However, an unforeseen obstacle looms before them: an unwanted interloper with designs on the magic crystal is out to win the heart of Princess Rose. If he is successful, it will serve to undermine the fellowship to the doom of all.
