A mysterious disease had plagued the planet Zephyr for thousands of years. It affected all the planet's people, the Moon Zephyrs, and the Sun Zephyrs; even the Xeno Zephyrs. Younglings were the primary victims of the disease; almost all younglings on Zephyr had been killed by the horrid disease. All but four. A young female Moon Zephyr by the name of Eclipse, a male Sun Zephyr by the name of Cyrus, a female Xeno Zephyr by the name of Viper, and a male Xeno Zephyr by the name of Xerus.
