When Relnor came to Earth, he brought his pet Remy alon (as a stow away). While the Harpians are pets to the Chevrotans, they are a formidable race. Fully sentient, the Remy are fast and persistent. Remy once got free from his enclosure and, in happiness, ran back and forth over a mountain range for two days. Well, there was a mountain range there before.
