Mechanical Sphinx
The Mechanical Sphinx was a creation of the Creator of the Crew of the Copper-Colored Cupids, a giant robotic sphinx designed to guard the Archives of the Cupid Homeworld from Chronon Fleas.
The Sphinx was “enormous, with a copper sheen to match that of the Clockwork Cherubs and a mouth full of fangs”. It was sentient and capable of being reasoned with, although it rarely spoke and even more rarely knowingly let anyone enter the Archives without eating them (most people who wanted to visit them, including the librarian himself, Bibliophile-962, had to sneak past the Sphinx using secret passageways). It did however let Jenny Everywhere, Juliet-178 and Arganthone-056 into the Archives in December 2020 in exchange for a promise of a Christmas gift, when they were looking for a way to thaw out Madame Tarsa from a magical block of ice.
