Plin, also referred to as Plin Minor, served as the terrestrial planet and homeworld for the Plinovian species. The Solodoe desired to terraform this planet, an action that would harm the Plinovians' native environment. This led to negotiations between the two species, held at Station Zeta; these talks collapsed when Arath Tarrex, a Jedi diplomat, absconded with the official seal of Ketas, the Solodoe ambassador. Ketas then blamed the Plinovian ambassador for the theft. The Plinovian ambassador, enraged by the accusation, spontaneously combusted, resulting in an explosion. As a result, Ketas ceased negotiations, committed to proceeding with the terraforming project.
The audiobook Dooku: Jedi Lost, penned by Cavan Scott and released in 2019, marked the initial reference to Plin Minor. The script of the audiobook provided the written form of Plin Minor's designation.
