Trivia

 * The fact that the Vulkan Series is only buyable with Zeta Credits is because the Vulkan Set is built for withstanding the extreme heat of the volcanic planet, Zeta.
 * Planet Zeta is named after Greek letter Zeta (Ζ/ζ) . The lower case (ζ) is used for heat flux across or through a plane in industrial materials technology. This possibly inspired the naming scheme of the planet as well as heat-resistance capability of Vulkan Series.
