Since the phrase doesn't give much detail, Des Forges could be anyone. It might be an author using a fictional name, or it could be a real person from history, literature, or even a local legend. Without further context, we can't really identify this 'Des Forges' precisely.
Hard to say. Without more information about 'Des', it's difficult to determine if it's a true story. Sometimes stories are inspired by real life but have fictional elements added.
You need to pay close attention to the details and look for clues throughout the story. Sometimes, it could be hidden in a special scene or behind an object.
I don't know for sure. It's possible that there's a kernel of truth in it, or it could be completely made up. Without more information, it's difficult to determine.
Maybe the Wolf Kwami has a special power that is different from the other Kwamis. A new villain wants to steal this power for their own evil plans. The story could focus on Ladybug and Chat Noir protecting the Wolf Kwami and its power. This would involve a lot of action and adventure scenes.
I'm not sure specifically as there could be many different interpretations in such a fanfiction. It might involve Naruto somehow coming into possession of a kwami, perhaps leading to new powers or adventures. Maybe he has to deal with the responsibilities that come with having a kwami, like a Miraculous in the Miraculous Ladybug universe.
Let's make a Kwami named Luma. Luma could be a Kwami related to stardust. Its Miraculous could be a star - shaped hairpin. The superhero with this Miraculous would be able to fly faster than normal superheroes, and also have the ability to create a shield made of stardust that can protect from most attacks.
