The Elfangor was the name of the Andalite Dome ship which finally came to Earth to aid the Animorphs in stopping the Yeerk invasion. It is named after the celebrated War-Prince Elfangor who died on Earth and broke the Law of Seerow's Kindness to give five human teenagers the power to morph. It was captained by Captain-Prince Asculan-Semitur-Langor.
