In a faraway kingdom, high up in the mountains, lived a people called the Jewels. They are a people of faith that live peacefully, surrounded by high tower walls that protect them from the dark Gem regions.

Every year, young Jewels are chosen to embark on a journey of purpose outside the kingdom walls to find their destiny. For the first time, Prince Emerald, along with Princess Ruby and twenty-two other young Jewels, will leave the kingdom and venture out into the dark Gem regions.

Prince Emerald has always had to keep his rebellious and headstrong cousin, Princess Ruby, out of trouble. Now out on their own, Emerald will find that the two evil sisters, Sparkles and Glitter, are working with strong evil forces and have other plans for the young Jewels, especially for the headstrong Princess Ruby.
