The Different Types of Grim Wars

The clavicular or key of Solomon is the grim war type that most academics tend to focus on because it has a very structured and set methodology. But you have to understand that this is only one kind of grim war, and it is one that although definitely the most popular is not indicative of every single grim war that we have. There are grim wars that read almost like a story and they're trying to tell you certain spells and rituals, but in a story based way. And there's something you might come across called a thesaurus spiritum or a treasury of spirits which for the longest time completely confused me.
