The wolf had been traveling for months, alone, surviving by eating fruits, plants, or carcasses of monsters that had lost in fights.
The wolf's journey to this place was actually quite interesting. When it ended up near Fargo from Bright, it had actually just followed the scent of blood. Somehow it ended up near the caves, and felt malicious energy from the man, making it want to kill him.
So it did, inexplicably saving two lives.
It also recognized the person it saved, but not too well, and it just left to resume meandering again.
After leaving the areas near the mines, it just went around and round, resuming its banal lifestyle.
This changed when after a few days, it felt a special force. The wolf followed its direction, finding a circle with many people coming out.
The wolf found them special, and it decided to stay there.
