lol these are golems, so yes. It's made from hardened dirt. However, htere is magic involved to allow it to use the abilities of what form it is. The golem dragon can breath fire, and has stretchable skin (like for the wings. it's not hard as a rock, and it does stretch.) The human knight golem looks like a human knight, due to the magic, and it's skin looks, and feels real. and the armour is a hardened version of the dirt. It makes it more realistic. XD
*The dragoness begins racing forwards, and begins to weave back and forth. a glaive goes by thm as she dodges, constantly looking back at the enemy. The dragoness then turned up and began flapping her wings to catch the air. She began climbing high into the sky, the zerg following.*
