In the previous life, the reason Gao Gong remembered this civilization wasn't just because they were fellow natives of the Robert Star System, but also for a very important reason—
The Orgrimmar people, the Hammer of Destruction, as a servant civilization, assisted the true Three Great Calamities in invading the observable cosmos.

Under its command, countless civilizations joined the dark side of the cosmos, becoming minions of destruction.
And the Orgrimmar people's title of "Hammer of Destruction" was gained during this period.
So, when Gao Gong first heard the name 'Orgrimmar people', he was startled, thinking that, due to his influence, the 'Fallen Empire' had arrived prematurely.
