A character who's been around for a few years, but I haven't talked much about! This is Midas.
Midas is a MIDAI unit; a type of alien AI salvaged after the war. They were narrowly saved from being decommissioned by Cain, and later became the blind god's eyes. His physical appearance is akin to a big server tower; this is the visual representation he uses to interact with people on the trawl, Terra's makeshift internet.
