The Changeling who assumed the form of Andrew Ellis was an outcast Founder who had been banished from the Great Link. He kept the body of the real Ellis in stasis, using a scalpel to give to illusion he had been attacked by an animal. Ellis was his primary guise during that time, also assuming the form of a Bajoran named Arak Katal. His colleague Crell Moset had become accustomed to referring to the Changeling as Ellis. After the Cardassian Union joined forces with the Dominion, the Founders chose not to target family members of known Maquis members, but the Ellis Changeling in the guise of Arak Katal disclosed the location of Tevlik’s Moonbase to the Cardassians. As punishment for defying the Great Link, the Ellis Changeling was stripped of his shapeshifting abilities.
