Human homeworld, combining Alpha Dawn and the Space Odyssey modules

Human homeworldHumans came from Earth. Yeah, this contradicts Alpha Dawn. I’m using the Space Odyssey modules as background, but combining it with Alpha Dawn.Earth is very far from the Frontier Sector, across the Galactic Core. Pi-tachyon communications don’t work when aimed through the Core because of a huge black hole and very high radiation levels. It would take a lifetime to reach Earth from the Frontier. Humanity’s first colony on this side of the Core region, to which the humans of the Frontier trace their origins, was rendered lifeless and uninhabitable by huge pulses of stellar radiation, but not before Vrusk contacted it using pi-tachyon technology and initiated an information/tech exchange.
