I am looking for a SF short story I read in an anthology published in Germany around the 70s or 80s:
I can't remember the full story but it has the following elements:
A boy or adolescent that is stranded on a planet: He is either a clone or a genetically engineered being. I don't remember how he ended up on the planet, whether he was left behind or was put there on purpose He has a type of telepathic connection to his other clones that are on a ship and who are reaching out to him. he can hear them in his mind and he is learning to compartmentalise this away in his mind to shut them out.
He is held in some form of laboratory and under the observation of either a researcher or jailor. One of them calls him a "Raud" image or "Fheid" image or some other similar name, as an indication that he is not an individual but just a clone.
He is allowed to leave the lab or prison at some point as a reward for controlling the mental influence from the other clones and interacts with 'local' people. I believe they were somewhat tribal. A young girl has to undergo a quest as rite of passage and he helps her at some point.
I believe the local tribe has some background story that they were fleeing away from a spaceship that had these clones/genetic altered people on them and are in possession of an item, I believe a piece of cloth that has to be held in the wind, that contains a recording of an emergency broadcast or plea for help, but they don't really understand the words of it.
Ultimately the clone spaceship find and catches up with the stranded clone on the planet. I am not sure but I seem to remember that he boy rejoined with them, because the mental pull was too strong for him to control.
Unfortunately not a whole lot to go by but hopefully someone else has heard of or read this same story.
I read the story in German in the late 80s as part of an anthology, but the story itself may have been much older than that.
