The Companion, by Maria Tiurina, via Faith is Torment.
“I call it “The Companion”. A story about two friends – a girl and her imaginary pet – who traveled for a long time, saw many beautiful places and met a lot of new people, creatures and animals who joined them as their journey continued. They arrived to something that resembles the edge of the world, and at first it might seem that their adventure has come to an end, but the girl is pointing at something high above that we cannot see, showing to her companion that there are more things to discover and enjoy together if only they wish to continue moving forward.”
