He is called the Ellimist. A being with the ability to alter space and time. A being with a power that will never be fully understood. He is the reason Elfangor came to Earth. He is the reason the Earth now has a fighting chance. And though his actions never seem quite right or wrong, you can be certain they are never, ever what anyone expects.
This is the beginning and the middle of the story. A story that needs to be told in order to understand what might happen to the future. The future of the Animorphs. The future of humanity. The future of Earth.
He is called the Ellimist. And this is his story...
As an unnamed Animorph lies on the brink of death, the Ellimist appears and recounts to him/her his origins as Azure Level, Seven Spar, Extension Two, Down-Messenger, Forty-One (Toomin) the Ketran and his transfiguration into the Ellimist as a final request to the dying Animorph. The Ketran race was virtually extinguished by the Capasins, who had seen transmissions of violent virtual Ketran games that had been broadcast into space and mistook them for a violent species that meddled with other ones. Toomin/Ellimist was one of the few survivors. These survivors became space nomads, seeking a replacement for their home Ket. Toomin became the leader of this group and was the only survivor when it crash-landed on a mostly aquatic moon. His mind was absorbed and kept alive at the bottom of the sea by a moon spanning entity known as Father that absorbed the information in the brain (or equivalent) of every corpse on it. After defeating Father at music, Toomin began to grow too intelligent for Father and defeated him, incorporating all the memories of corpses on the moon, eventually becoming a blending of minds.
After he defeated Father he began to wander the universe without purpose until he started to resolve conflicts and crises under the name Ellimist. The Ellimist worked like this for several thousand years until he encountered the Crayak, who existed to destroy all life in galaxies, a strong antithesis to what the Ellimist had come to stand for. Crayak engaged Ellimist in games that had entire planets at stake. Ellimist did not fare well and lost far more often than he won. Losing motivation to continue fighting the Crayak, the Ellimist temporarily retreated to the Andalite home planet, possibly beginning his worship as an Andalite god. (The Ellimist created an Andalite body for himself after taking bits and pieces of memories from himself and all the people he knew and loved, thus created the Andalite race in his own image.) The Andalites at the time were not the advanced civilization but a primitive collection of tribes. By living on the planet as an Andalite, the Ellimist learned that the key of survival was to create as many offspring as possible; although so many die, with repeated efforts life could multiply faster than the Crayak could wipe them out. With a renewed vigor, the Ellimist fought the Crayak, creating the Pemalites, creators of the Chee, who spread quickly throughout the galaxy (until they were destroyed by Crayak's own creations, the Howlers). Although, the Crayak eventually destroyed the Ellimist physically by luring him into a black hole, the Ellimist found himself fully integrated into the fabric of space-time. Soon, both the Crayak and the Ellimist recognized direct combat to be much too dangerous for themselves and space-time itself. To prevent such catastrophic damage, the Crayak and the Ellimist agree to construct the intricate "game" they are seen to play in the Animorphs series.
- Chronologically, this book ends within the first few moments of the last book Animorphs #54: The Beginning, however, the Ellimist Chronicles was released with Animorphs #47: The Resistance, approximately 7 months before its release. The moment at the end confirmed the death of a major character, which was wildly speculated and anxiously discussed by fans, and still is today one of the most discussed topic in the series.
- The bottom right of the pages in this book have a flipbook just like the rest of the Chronicles and the numbered books. However, it is not a morph; instead, the Ellimist as depicted in the cover illustration gradually disappears into a cloud of smoke.
