The Shadowlands invasion was a period of sixteen years in which the Shadow Lord broke the Belt of Deltora, scattering its gems, disestablished the monarchy of Deltora, and took possession of Del. During this time, the Shadow Lord exercised ultimate power and absolute control over Deltora, its citizens, and laws. The palace of Del became the headquarters for the Shadow Lord and his will was enforced by Grey Guards and other servants. The invasion ended after Lief discovered himself to be the heir to the kingdom of Deltora, and used the Belt to banish the Shadow Lord after its completion.
