Mercator Lambert first became aware of the Universal Primate Captivity Crisis while on a remote 7-year study abroad venture at The House of Planet-by-the-Way where they earned their Astrobiology Doctorate . A dedicated Doctor through and through, Mercator has always sought to offer aid not just to the Apskellion, but to the apes of all worlds, including those of Earth. Now, as their mission leads them to Earth, Mercator and the Doctors are dedicated to the liberation of the primates in captivity there.
