My versions of a guild navigator from "DUNE". Kinda went with the description from DUNE Messiah of Eldric. I wanted to maintain that essence that the navigators are kinda nasty to look at.
Guild Navigators spend their lives in micro-gravity tanks filled with an orange gas created from the spice. From this exposure the navigators have mutated to have webbed hands and feet while most of the rest of their bodies are atrophy and useless. The navigators use the spice in the space travel technique of spacefolding.
5* Great stuff.
