God
Khan's expansion strategy proceeded smoothly. No tribe could hope to oppose him, and his strange abilities put him closer to a deity rather than a strong warrior in those primitive minds. He barely had to do anything to make the Scalqa fall to their knees.
The quadrant's ships also removed problems connected to the vast scope of the mission. Baoway wasn't immense but remained a planet, and Khan wanted to handle every conquest personally. That could take decades on his own, but the various vehicles greatly shortened the process.
Nevertheless, new problems surged as the expansion continued. Khan acted personally to avoid pointless bloodshed and add assets to his force. He wanted the Scalqa's strength for multiple reasons, but their numbers rose too much too quickly.
