Valt Minor, named in honor of Valt, is the homeworld of the Valtese and historically, the former homeworld of the Kriosians.

The planet is the site of the Temple of Akadar, the historic seat of power for the empire ruled by Valt and Krios, the two brothers who were the progenitors of the Valtese and Kriosian races before their love for Garuth caused a rift that would persist until the marriage of Alrik of Valt and Kamala of Krios in 2368.
