Even as their society reached its technologicalpeak, however, the Chozo felt their spirituality wane. Their culture was steeped in prophecy and lore, and they foresaw the decline of the Chozo coinciding with the rise of evil. Horrified by the increasing violence in the universe, they began to withdraw into themselves, forgoing technology in favor of simplicity. Tallon IV was one of several refuges they built-a colony bereft of technology, built of natural materials and wedded to the land and its creatures.

 

   The years passed, and in time a great meteor crashed into Tallon IV, sending a massive spume of matter into the atmosphere and impregnating the land with a cancerous element known as Phazon. This element immediately sank into the earth and water, poisoning life wherever it bloomed. Most plants and animals died, while others mutated into hideous forms.

 

   The Chozo called upon all of their knowledge and technology to control the power of the Phazon, but their efforts were doomed to fail. All they could do was build a temple over the crater at the impact site, seperate the Phazon core, and seal it away. Believing that someday a savior would return to the planet,the Chozo left for an unknown destination, leaving behind nothing but engraved accounts of their time on Tallon IV.
