Final answer:
The narrative provided does not mention Radulf or the mark of the Divine Star. It describes the character Ethelred breaking into a hermit's residence in inclement weather. Without additional context, we cannot ascertain Radulf's actions related to the Divine Star.
Step-by-step explanation:
The excerpt you've provided appears to be from a narrative, possibly Gothic or classic literature, rather than a text about a historical figure named Radulf or an event involving the mark of the Divine Star. From the passage, Ethelred is described as a bold and somewhat intoxicated character who decides to forcibly enter a hermit's abode without parley. He does so by breaking the door with his mace, despite poor weather and the approaching tempest. Unfortunately, without further context, it is not possible to determine what Radulf has done to everyone with the mark of the Divine Star, as this specific action is not detailed in the given text. Therefore, with the information provided, I cannot accurately answer the student's question regarding Radulf's actions.
