A Handler was most likely a special type of human created by the Tleilaxu to care for and breed Futars, in their war against the Honored Matres out in Human Scattering-space. For the futars who found themselves encaptured and imprisoned on the no-ship kept on Chapterhouse, they constantly clamored in their need to find "their Handlers". Handlers were taller than most humans, had a keen sense of smell; and had darkened pigmentation around the eyes, akin to raccoons.
