Right, shower thoughts. How the hell do the poor turds in Westfall make golems.
They are clearly shown to be made out of sacks and some mild machinery, and even in Deadmines, the big one is made out of a barrel and some sticks.
This gets me wondering, in WoW, it doesn’t take much to make a Golem, does it? It makes me think that just about anyone could slap one together if they wanted. Like, how do they work with such minor metalic parts. Is it some kind of magic?
I would say they are from when Westfall was a thriving farmland. We see golems like these in other parts of the world too. They could be leftover (seeing as in Westfall many have malfunctions) and very old from the past.
This is in fact what the Warcraft Bestiary suggests:
The terrifying Harvest Golems are mechanical constructs programmed to hunt down and terminate the Human inhabitants of Westfall . Though their origin is uncertain, some believe that only the wily Goblins could have created these mechanical monstrosities. Others speculate that the Defias Thieves had the Harvest Golems built to scare off the local inhabitants of Westfall so that they could run their smuggling operations with greater impunity. Whatever the case may be, the Harvest Golems have done their jobs well - eliciting terror in anyone foolish enough to roam the fallow fields of Westfall alone.
Now why would Stormsong Valley be utilising Harvest Golems when they’re apparently specifically Defias or Goblin tech intended to harass Westfall? Why it’s obvious of course:
I just figure they are human creations to assist in farm labour thus their presence in Stormsong Valley and Westfall. As for the Westfall ones. We see Goblins making them for the Defias Brotherhood, perhaps rewiring them to terrorise the locals. We know they are used by Goblins in other areas so perhaps it simply was a goblin construction to begin with. Small pet ones description shows their use in farming and we know of their use doing that. So chances are their construction originally was during much better days for Westfall and with the Defias turning them to a darker purpose. Now without control they are a bit rampant and overloading and attacking anyone.
Really, just explain them as originally made during better years of Westfall and turned to the Defias need later on. As for Stormsong Valley we see them used again, makes sense kingdoms trade technologies and well, they didn’t have a Defias problem.
goblin/gnomish inventions.
Keep in mind Kul’tiras was accessible prior to the third war by merchants from over the world.
Goblins are still mostly neutral as well.
So it could still be of aforementioned origins.
The humans in Borean Tundra also had harvester golems, my own headcanon is that they were simply reverse engineered and used as automatons to ward off danger/help harvest the produce.
Though if you watch them they seem to be the most janky automatons in the setting. Worst golems tbh.
