Echelon

Echelon is the planet where Ed and his pirates where forced to knit in a life of servitude, before escaping and becoming the Boy Captain of the Knit-Wits. In her retconned origin story, Screenshot finds her tablet in the wreckage of a ship coming from Echelon, piloted by a green-blueish alien pilot with a rectangle head and two white dials on his chin, who dies of a common cold given to him by Screenshot.
