The Charpactin are a race of sentient fungoid creatures who encountered the T'au Empire's Fe'saan Water Caste diplomats during the Fifth Sphere of Expansion. They communicate entirely in bursts of ultraviolet colour, whose strobing emanations prove surprisingly effective at subduing and transfixing living beings — making them docile and amendable. After the Water Caste observed this in action, the T'au Empire quickly negotiated a client-state treaty with the Charpactin and have since drafted many of the fungoid creatures into its growing Edification Corps.
