The Tinmizer machines in Nektropos Castle are sort of a development error. They should never have been placed there, at least not in the iron guardian model we all see. Tinmizer did make a construct was said to be resting within a secret vault of the castle. It was called Tinmizer's Ominous Army. The bit of lore around this one clockwork army led to the iron guardian population you see in the zone. Does the contraption still exist in the castle, hidden for ages? The designs for such a thing do exist and were obtained by the T.B.I. I wouldn't be surprised if some of these clockworks still roam the hills of Steamfont.
