I'm not sure specifically who 'Julian Rupa' is in the context of art science fiction. There could be many artists or creators with that name or it might be a relatively unknown figure in a niche area of this genre.
It could be about a group of archaeologists exploring an ancient site in Rupa, Romania. They unearth a strange artifact. Soon after, they start having nightmares. One of them begins to act strangely, as if possessed. The others notice that he has a strange mark on his body that resembles the symbol on the artifact. They realize that they have awakened something evil and must find a way to put it back to sleep before it consumes them all.
I don't have a specific Rupa Romani horror story to share directly. But in general, horror stories from Romania often involve elements like old castles, dark forests, and superstitions. Maybe in a Rupa Romani horror story, there could be a spooky old house where strange noises are heard at night. People might feel a sense of dread as they approach it, and once inside, they discover things that are not of this world.
One aspect is the role of family. In Indian culture, family often has a major say in relationships. So in the stories, we may see how families either support or oppose the lovers' union. For instance, in some stories, the parents might arrange marriages which conflict with the characters' own love interests.
I'm not sure exactly as I haven't read this book in detail. But generally, it might be about various animals and their adventures, perhaps in the context of the 'angry river' which could be a setting that affects their lives.
Since I haven't read the book, I can't say for sure. But it could be different kinds of animals like bears, deer, or birds that live near the angry river.
