The Terrans are a young species with psionic potential. The Terrans of the Koprulu sector descend from the survivors of a disastrous 23rd-century colonization mission from Earth.
From the ashes of the Confederacy arose the Terran Dominion, a nation dedicated to protecting humanity under the watchful rule of Emperor Mengsk.
“The time has come, my fellow Terrans, to rally to a new banner. In unity lies strength; already many of the dissident factions have joined us. Out of the many, we shall forge an indivisible whole, capitulating only to a single throne. And from that throne, I shall watch over you! From this day forward, let no human make war upon any other human. Let no Terran agency conspire against this new beginning. And let no man consort with alien powers. And to all the enemies of humanity, seek not to bar our way, for we shall win through, no matter the cost!”
– Arcturus Mengsk
