Planet Voldor (惑星ヴォルドール)
62% land mass is covered in marshes & is described as a blue & green planet. Its principle exports are lumber, fruits & spring water with zero strategic value.
Voldorians were originally modified felines.
The Windermereans discovered the polyphenols bound to the Voldor bicarbonate has high concentration of seidznole. By mixing water from Voldor with Windermerean apples, it creates seidznole in the body that triggers the Var. Other planets' ruins most likely have water with similar composition, making it efficient for Winderemere to articially spread the Var Syndrome by using the water & apples. They then control the victims with the song of the wind sung by Heinz.
