The Yellow Nation has been using tech and massively improving it since the war began. They've created mechanical limbs and robots to aid them in any way necessary. They have started to sell their mechanical limbs to all others as a way to even the playing field if they were to get back involved in warfare. They've created 3 versions of their machines dubbed, "Gilded Machinery". Versions 2 and 3 have since been banned in warfare and sent to The Mechanical Graveyard.
