While the Goetic spirits are often talked about in full, or perhaps specific Goetic spirits such as the Kings are mentioned in other tales or hierarchies. Not many of them get dedicated texts, so it's great to have a full text dedicated to one of these. There are invocations and evocations present in Solomonic fashion, while still bending to the Left Hand Path. It's not a long read, but the way it works in the themes, ties them to praxis and the Goetia itself, it's all fantastic. I hope to see more of these from Asar, and from seeing Rites of Marbas, I am excited to see more from him.
