I'm not sure specifically as I haven't read this novel. But generally, in a romance fantasy, there might be elements like a unique world setting, and the 'lord baby' could be an interesting protagonist. Maybe the 'cash' part implies some sort of financial or resource - related sub - plot within the romantic and fantasy elements.
The phrase 'lord baby runs a romance novel' is quite ambiguous. One way to think about it is that 'lord baby' could be a character with a title of 'lord' who is in a form of a baby, and this character is somehow involved in the operation or creation of a romance novel. Maybe he is the main inspiration for the novel, like the events in the novel are based on his own experiences or desires in his strange baby - lord world.
The Lord of the Rings was a classic fantasy novel. The novel described the adventures of Hobbits, Dwarf Golden Boots, Elven princes, human knights, and the wizard Gandalf in Middle-earth. It involved various magical elements such as magic, Dwarf Golden Boots, Elven culture, and wizard techniques. This kind of novel often used fantasy and magic as the theme to describe the protagonist experiencing various adventures and challenges in a mysterious world accompanied by various magical creatures, mysterious rituals, and supernatural powers.
The Lord of the Rings was one of the masterpieces of Western fantasy literature. It told the story of the adventures of Hobbits, Dwarves, Golden Boots, half-elf Gandalf, and Ringwraiths in Middle-earth. In this fantasy world, they face various dangers and challenges, and at the same time discover the story between humans and the Lord of the Rings. This novel is widely regarded as the foundation of modern fantasy literature and has a profound impact on the development of Western fantasy literature.
It could be Bellatrix Lestrange. She was one of Voldemort's most loyal followers and was quite obsessed with him. It's not hard to imagine in a fanfiction world that she might have had some sort of relationship with Voldemort that led to the birth of a baby.
One possibility could be that the baby is a result of some dark magic experiment. Maybe Voldemort created the baby as a new vessel for his soul, more powerful than his previous Horcruxes. The story could then revolve around the baby growing up under the influence of Voldemort's followers, who see it as the future of the Dark Lord's reign.
For a fantasy story, consider the name Thorne. It gives an impression of something a bit dangerous and edgy, like a thorn on a rose. Arwen is also a great name, often associated with elven beauty and grace in fantasy literature. And how about Gideon? It has a strong and heroic sound, suitable for a brave character in your fantasy tale.
The Lord of the Rings is primarily fantasy. It features elements like magic, mythical creatures, and epic quests, which are typical of the fantasy genre.
