Two humanoid beings, wholly enveloped in unknown armor, Markham watched, feeling a familiar presence. Their size and feeling are too similar to humans. Could they be remnants of the Nimeier civilization?
No, their technological level is far superior to the Nimeier people, and they've evolved in a different direction.
As the supreme commander of the human expeditionary force, Markham, displaying the calmness befitting of a five-star general, walked over, "I am the supreme commander of the human expeditionary force. Can you understand me? Do not attack!"
Markham stopped the warriors who were preparing to fight. He somewhat regretted having sent all the top mechanized fighters to Kepler.
One of the armoured beings took a step forward, speaking in standard human language, "Don't panic, the war is over, star-seeding humans."
