Ē'aluth (Eealus) is best known as the home to the Xi'an Empire's prime nature preserve, Ko'li (Ē'aluth III). It was deemed an ideal conservation system since the other planets were unfit for habitation and offer little in the way of resources. Fear of smugglers and invasive species finding its way onto Ko'li means that customs enforcement is especially strict when entering or leaving Ē'aluth.
