Khan and Alexander discussed the other six Excellencies for a while before duties requested their presence elsewhere. Alexander was a jack-of-all-trades in politics, so he went wherever the planet needed him. Meanwhile, Khan had more specific tasks to attend to.
A lesson with Moses, Roger, and Professor Parver unfolded. Khan kept hammering down the fundamental theories of his alien arts, gradually starting to accept questions to clear eventual doubts. The trio was nowhere near understanding those explanations, but Khan had never expected the process to be easy.
The lesson was long, but an even longer procedure followed. Khan met with Prince Thomas again to settle all the details related to Moses and Roger's early departure. That part was still manageable, but things became complicated once the topic moved to Khan's eventual disappearance.
