Conveniently that you focused on that, and that alone, instead of also where I brought up Heartlands. You know, the book that’s even more recent lore than Anduin mentioning the ancient Arathi.
We send their armies our grain while the Stromic starve. We send them our fighters while our children grow up not knowing their storied legacy
“The 7th Legion, the Stromic army!” The raider’s wolf mount rose up on its hind legs and howled at the rising moons. “They march! We are under attack!”
While it was reasonable to expect the citizens of Stromgarde had retired for the night, there was also no sign of the 7thLegion or Stromic army below.
The Mag’har leader, still on her mount, was perhaps half a mile distant, her axe swinging as she fought off one hapless Stromic soldier who dared get too close.
She was in a farmstead—a human one. It seemed she’d been swept some distance from Go’Shek, to Stromic holdings.
The 7th Legion were mighty, but even before the battle Geya’rah knew the Stromic were fewer in number.
“There will be no battle here! There is no honor in this slaughter! The Kor’kron and Mag’har will hold. I call upon the 7th Legion and Stromic army to do the same!”
It also illuminated the terrible cost of the fight. She could see bodies
strewn across the Highlands, many fallen on both sides—Stromic, Mag’har, 7th Legion, and Kor’kron.
Jaina stepped to one side as Danath Trollbane walked out onto the field, leaders of the Stromic army following close behind
Marran took a step toward Jaina, but was restrained by a Stromic captain.
I know you don’t like having your headcanon challenged, but fact of the matter is, Anduin isn’t speaking of the modern day Stromic. He’s speaking of the ancient Empire and the Tribe, both of whom have fallen into nothingness by this point. Before we reach Hallowfall Anduin comments on the Earthen calling him Arathi.
Anduin Wrynn says: Some of them have been calling me Arathi. Like the ancient human empire. I… wonder how they know of it.
If the Stromic were called Arathi, why would Anduin say they are calling him Arathi like the ancient human empire?
