The term was used to describe both the Rakian sandworms and Leto himself. Upon his death, Leto's worm body disintegrated, thereby releasing hundreds of sandtrout into the desert, which would eventually lead to the re-emergence of sandworms on Rakis. Moreover, Leto had foreseen that upon his death, the worms that grew from the sandtrout would maintain a pearl of his consciousness, and that he would live on in an "endless dream" within the worms. Thus, the term "Divided God" would refer to the division of Leto through the sandworms.
