It was during the late create era that Hrnian armada arrived into Solar System - they were peaceful explorers endeavoring interstellar trips only for one purpose - gathering of the knowledge. All their philosophy was based on learning about all form of life and exploration of different ecosystems. Probably it originated from their old religion, which imposed the research for origins. Hrnians did not evolved on the Hrn planet on which their new history begun - there was no clues, no records, that could suggest what happened, why they appeared on Hrn, when, and from where their ancestors came. Later, when they developed their civilization and discovered this fact, research for the planet from which their ancestors arrived became their obsession. After arrival on Earth they established a colony. High level of Earth's atmosphere oxygen was poisonous to Hrinians, that's why they were obliged to wear protection suites, which protect them also against all kind of microbes and parasites. On the left you can see a small landing ship - one of a dozen on which they arrived on Earth. In distance, on the right, you can see their colony. The picture was taken just a couple of years after the landing, so colony was still relatively small and served mainly as a base for small ships carrying scientific teams to all regions where research works were undergoing. During next 740 years Hrnians prepared to next interstellar step, to a star distant of 35 light years from the Solar Sytem. They did not aim to stay on the Earth - after they renew and refueled their ship (which stayed on solar orbit behind the asteroid belt) they settled out for next trip. (MORE DETAILS IN COMMENTS)
