Medx Homunculi

The Medx homunculi is an unsettling little creature, looking uncannily like a bony human scaled down to thirty centimeters in height. They inhabit the wispy treetops of Gravlex Med and - while not sentient - are quite clever for animals. The striking resemblance between these chittering creatures and the species that rules the Galactic Republic is a private joke among the Anx.
