The darkness was also a benefit to Karl, as he could hear the Goblins running into various things around town, where the lights in the houses had been broken or turned off. They might have a sneaky dart gun, but if they couldn't see him, then it wouldn't really matter what sort of weapons they had, they wouldn't be able to hit him.
With that in mind, Karl shifted into the shadows of an alcove and waited for more Goblins to be attracted by the noise and the smell of blood.
He could hear Hawk hunting in the distance, the short shrieks of Goblins as they were assaulted from above, cut off before they could get a full word out, but Hawk's narration said that he was still high in the sky, using the dark to his advantage while attacking down into the fog.
