Kreacher is a very traditional character. His influence on Harry could mean that Harry is more into the old magic. He might be taught spells and incantations that are not commonly known in modern wizarding society. Also, Kreacher's loyalty to the Black family could make Harry more protective of the remaining members of the family and their heritage.
One common theme is redemption. Kreacher has done some not - so - nice things in the original series, and many fanfictions focus on him finding a way to redeem himself. For example, through helping Harry or the other good characters.
A fanfic might explore Kreacher's relationship with jewelry in the context of his loyalty to the Black family. He could have been tasked with taking care of certain precious jewelry items over the years. The story could show how he values these items not just for their material worth but also for the family heritage they represent. For instance, a ring that was passed down through generations and how Kreacher ensures its safety during the chaos of the wizarding wars.
In fanfiction, Harry and Kreacher could be seen exploring the different terrains of Westeros. Maybe they stumble upon the Iron Islands. Kreacher could be fascinated by the Ironborn way of life while Harry tries to find a way to use their naval power for some greater good. Or they could end up in King's Landing and face the political intrigue there.
It would be a unique take on the Harry Potter story. Kreacher is a complex character. He could raise Harry in a way that emphasizes self - sufficiency and loyalty to a fault. Harry might not be as eager to jump into the fight against Voldemort as in the original story. Instead, he could be more focused on protecting his own little world created by Kreacher. Also, his magic could develop in a more unorthodox way due to Kreacher's unorthodox teaching methods.
It could be really interesting. Kreacher, being a rather complex and initially prejudiced house - elf, would raise Harry in a very different way from the Dursleys. Harry might grow up with a deep knowledge of the Black family secrets and traditions. He could also be more in tune with the wizarding world's darker elements from a young age.
Yes, he does. Maybe Kreacher, as a character in the Harry Potter world, is intrigued by the different interpretations and adventures of Harry in fanfictions. Fanfics often explore new aspects of characters that might be appealing to him.
They might interact with Jon Snow. Harry could see a kindred spirit in Jon, both being outsiders in some ways. Kreacher might be initially distrustful but would come around. With Daenerys, Harry could be in awe of her dragons, and Kreacher might be cautious. They would also have different reactions to Tyrion. Harry might see his intelligence, and Kreacher might be a bit wary of his Lannister name.
There's a fanfic called 'Kreacher and the Lost Heirloom'. In this story, Kreacher embarks on a journey to find a valuable heirloom of the Black family. It's full of mystery and adventure, with Kreacher's loyalty to his family's memory being a central theme. The author does a great job of depicting Kreacher's complex personality.
In this fanfiction, the plot might revolve around Harry's struggle to balance Kreacher's teachings with the values of the wider wizarding world. He could face discrimination from other wizards who are suspicious of his upbringing. Meanwhile, Voldemort might see Harry as an even greater threat because he's been raised by Kreacher. Kreacher, being protective, tries to shield Harry from the Dark Lord, but Harry realizes he has to take a stand. This could lead to a series of battles and adventures where Harry has to prove himself not just as a wizard, but as a person with his own set of beliefs.
