- "It was round. As round as a plate. A very large plate. From one side to the other, the diameter must have been half a mile. It was covered by a transparent dome. Clear glass, or whatever it is the Andalites use for glass. And within the dome, protected from the crushing force of the water, was what looked very much like a park. A park, in a plastic dome, at the bottom of the ocean. There was grass, more blue than green, but it still looked like grass. There were trees like huge stems of broccoli. And other trees like orange and blue asparagus spears. At the center was a small lake, crystal-clear blue water. From the water grew fantastic, transparent green crystals in shapes like eccentric snowflakes."
The GalaxyTree was the name of the Andalite Dome ship Elfangor and Ax were stationed on before the start of Book #1: The Invasion, where it was in battle in Earth's orbit against the Yeerks. Ax was inside the dome because he was an Aristh and couldn't be part of the fight. The dome was then separated from the rest of the ship for better maneuverability against the Yeerks, but the ship was destroyed by Visser Three's Blade ship, and the dome crashed into the Pacific Ocean, where Ax waited for weeks, until he was rescued by the Animorphs in Book #4: The Message. Its captain was a War-Prince named Nerefir.
