Translated as “Xhirináchenande-ahé” in its own language, the planet was named because of the orbit of its moon, an evil sentient being that fed upon negative energy and exerted a negative force upon its inhabitants, causing them to bitterly war with each other for a period of 3 years and live in a time of peace for 2 years; a cycle happening every 5 years. This resulted in the destruction of their society at their own hands for 3 years, then it’s rebuilding for 2 years, until the cycle started again. Despite this destructive cycle, the Xhir race became an advanced species, technologically progressing in peacetime, aided by the creation of a select group called the Gentri. The Gentri discovered the sentient existence of their moon and with the help of the Doctor, planned and built the weapons which ultimately destroyed it.
