Ephemeris, also known as the Creature Collector, was a vast interstellar machine in Ratchet & Clank: All 4 One. It was The Loki Master's base of operations. It was originally a Servitor drone that was repurposed by Dr. Croid, but later modified by the Loki Master and Nevo Binklemeyer. Ratchet, Clank, Qwark and Nefarious were kidnapped by Ephemeris and transported to planet Magnus along with the Light-Eating Z'Grute. Ephemeris used a Versatron energy dock to charge it's power and emitted a High-frequency sonar ping in order to prevent ships from flying into it.
