Convenient you cut off the next part in your reply and made no attempt to dispute it.
There was a fair bit more specific lore about the Eradar, and it all conflicts with them being corrupted Draeni. You can’t ignore this when it comes to the context of Draeni origins.
This is only technically correct. But by the same technically correct conclusion, we can also conclude they did not share origins with the Eradar. In the context of WCIII and the current Eradar lore at the time, it is pretty explicit by what Akama is talking about.
“The orcs slaughtered my people, and their demon magics consumed our world. We that are left will reclaim what we can. Of life and honor amongst the ashes of our history.”
Which I suppose can be recontextualized if read charitably, even though it wasn’t the orc’s demon magics that consumed his world.
“But now, with Lord Illidan behind us, we will fight back and retake our ancestral lands.”
But this can’t, unless he had some strange idea Illidan was heading to Argus.
And then there is the RPG, written by the same people who wrote the original Warcraft lore. Why are they so mad at orcs, when it is their own corrupted Eradar brethren that command the orcs? Unless at the time that’s not what it was.
