One night, Adin, a blacksmith of Del, had a dream of a belt of metal with seven medallions, with chains to connect them to each other. In each medallion was one of the seven gems of Deltora. Adin created the belt the belt that he dreamt of and when he finally finished it, he took the belt and traveled to every tribe to persuade each of them to give him their gem.
In the beginning the tribes were mistrustful, but they slowly went along with it to save the land. They gave him their gem, and Adin placed each of them in the spots of the belt. When in the right combination, the first letter of each gem spell the name DELTORA:
D - Diamond
E - Emerald
L - Lapis Lazulli
T - Topaz
O - Opal
R - Ruby
A - Amethyst
The tribes walked together with Adin and in unity they fought and defeated the Shadow Lord, driving him back to the Shadowlands. The belt only works when Adin or his heir wears it.
However, the Shadow Lord, after many generations, took control of the royal family by making his servants the kings' and queens' closest advisors. Eventually, it became the custom to wear the belt only on they day in which the heir became the king or queen. It was in the time of Endon that the Shadow Lord finally seperated the gems and took control of Deltora.
- The primary use of the Belt of Deltora was to keep the power of the Shadow Lord at bay, so that he could not invade. This will only work as long as the ruler of Deltora has the trust and faith of the people.
