The name 'Hastar' doesn't immediately ring a bell in mainstream religious or mythological canons that I'm familiar with. It could be a very local or newly created concept. Maybe it's a name from a very specific cultural or spiritual group that not many people outside of that group know about.
The name Hastar is not very common in a general sense. It could be a unique name within a particular family or a regional name. If it's related to a real story, it might involve family heritage, like how the name was passed down through generations, and the stories associated with the family members who carried this name. Maybe it's a story of love, sacrifice, or perseverance within the family that has been tied to the name Hastar over time.
Jiang Feng of the God-slaying Temple was a novel written by Sir Kakarot and Little Raccoon. The novel was full of ups and downs and was exciting. It was described as a good book with excellent plot and writing. It was serialised on different websites and had different chapters that were free to read. However, the search results didn't provide any information about the details of Jiang Feng's novel. Therefore, he could not provide a more detailed answer.
Since I don't know the details of the Hastar real story, it could be anything. It might be a story about a local hero named Hastar who did great things for his community, like building a school or helping the poor. Or perhaps it's a story of a discovery made by someone named Hastar, which changed the lives of people around them in some way.
