Lore can be seen as the back story. It might include details about the origins of a place, the past of characters, or the hidden histories that shape the current situation in a story or game.
The World of Warcraft lore novels contribute in many ways. They expand on the races. Take the trolls, for example. The novels might tell of their ancient tribes, their shamanistic ways, and how they came to be in different parts of Azeroth. They also detail the relationships between different races, like the uneasy alliance between the humans and the dwarves at times. By doing so, they create a more vivid and complex world that players can immerse themselves in when they play the game. The novels can also introduce new concepts and magic systems that later get incorporated into the game in some form.
A lore graphic novel is a type of graphic novel that often focuses on the backstories, myths, or detailed world - building aspects of a particular fictional universe. For example, in a fantasy lore graphic novel, it might explore the history of magic, the different races that exist, and how their societies were formed. It's like a visual encyclopedia of the fictional world's lore.
The Lore TV show is indeed fictionalized. It takes elements from various sources and weaves them into fictional narratives that may or may not have real-world inspirations, but are not based on actual events.
Fictional lore is basically the background story and world-building in a fictional setting. It's made up of details like history, culture, and rules. For example, in the Lord of the Rings, the lore includes the history of Middle-earth and the different races and their powers.
