Thank you )) I added to add this picture because somehow I decided to call this story "The Elephant" - even before realizing that it's somehow is going to be related to the Elephant - just because the aliens have elephant ears and some have elephant trunks. Then I postfactum realized that it must somehow be related to The Elephant - because it's going to be the key to the mystery of the strange appearance of locals and of this world in general. The question remains - what "The Elephant" actually is )
