Yes, there will be. J.K. Rowling has been quite engaged with this series and given its popularity, it's very likely she'll continue writing more Cormoran Strike novels.
As of now, there is no definite information regarding a new Cormoran Strike novel. The previous novels in the series have been well - received, which might suggest that there could be more in the future. But we have to consider that the author, J.K. Rowling, is involved in multiple projects. She might be exploring new ideas or working on other stories. The publishing world also plays a role. If the publishers see a high demand for a new Cormoran Strike novel and if J.K. Rowling has the time and inspiration, then it's very likely that we will see a new one. But until then, we can only wait and hope.
The Star Map of the Blazing Strike was the appearance of a godly item for the Wizard class in World of Warcraft. In order to unlock the appearance of the Map of Stars, one had to complete the Mage Class's Divine Artifact Quest and reach Divine Artifact Knowledge Level 5. After that, there would be a chance for the monsters in Surama to drop unlocked items. After transforming into a star map, he could also unlock different colors and progress. As for the specific quest location and NPC, the search results did not provide any relevant information.
I don't think so. J.K. Rowling seems to be taking her time between novels in this series. And since there are no hints or news about a new one, we may have to wait a while.
