Steve is part of a robotic race called Drones, which was (partially) explained in The Agency. That was kinda like a prequel to the Tempora set of stories, which then led into the current Outside the Wall set(I'm trying to structure them like story arcs). Drones aren't exactly like droids in that they are in fact living beings and not entirely synthetic, but the distinction isn't too important in most of these stories. At least, not yet...
Yeah, Vorpal society is something I plan on exploring a bit more in some of my later writing. Some parts of it might definitely seem better at first, but it comes at the cost of being completely incompatible with other races. When Vorpals recognize someone as not one of them, the response is frequently to just attack with intent to kill. Dapper just happens to be one of the exceptions to this general rule(at least on occasion; in some of my other stories, you will see him as being not very consistent), and has enough charisma/clout to talk down other Vorpals.
Haha yes afterwards I was like it is a drone, in the next part you mention she if from the fire nation then clicked a bit again I was oh yeah Steve ain't from those parts. Thank you for clarifying though it does help, I think what mainly got stuck in my head is that he started "human" .
Yip Dapper definitely is the shit, a bit of gentleman swag mixed with a psychopathic killing machine. Awesome.
