replying to these three at once cause they feel like they're all more or less getting at the same thing, and not to be so dismissive but all that is pretty much setting lore nonsense IMO, you haven't given any actual reasoning beyond seemingly repeating 'well they're part of ebberon's lore so they should stay that way', adhering so strictly to the specifics of their creation is needlessly restrictive in a way that doesn't get applied to the majority of the other species, you don't get people saying 'well you can't have dragonborn in X setting because there aren't dragons and dragonborn were modified from dragon eggs', they just say 'here's this species of cool dragon people, they exist here', golems are standard fare in most settings and wizards are inventing new experiments and creations all the time, and warforged are pretty much just a more advanced golem when you get down to it, 'once upon a time there was a wizard who thought it'd be pretty neat if he had a sentient golem, so he figured out how to make the first warforged and eventually spread the technique far and wide, at one point it was discovered the warforged have their own souls and were made their own people' boom, done, how warforged exist in any setting whatsoever without magitech or artificers or the war or anything else.
