The planet Gliese has always been considered one of the best for colonization. It is very similar to Earth, it has a stable atmosphere, there is water, there is flora and fauna. Moreover, the colonial ship sent there was almost undamaged upon landing. Everything should have worked out - and it didn’t. There was no settlement on Gliese, and thousands of people simply disappeared. Why? Yes, because Glise has its own intelligent life, which turned out to be not at all happy with the aliens.
