The clever, charming (and oh so cute when he's grumpy) Cid! 5.3 made FFXIV be very present on the mind for us all (certainly for me, I'm Very Emo) - that said Cid hasn't actually been present for a hot minute.... but who knows, there's a chance he might get a return to a slightly bigger role if next expac is what it seems like it'll be.
but for now, i wonder what this inventor does to let off steam for his own engine...
