A Snake

Due to being disturbed, Arthur created a ball of fire which then floated in the air and followed the tree trunk. It had a sun-like shape, so its light spread everywhere.

Isabel and Nova stared at the fireball, the former showing a satisfied expression because her vision finally became clear.

Of course, just because there was light around didn't mean the tributary became less terrifying. If an ordinary person followed Arthur and the others now, he would surely be very scared.

When you looked ahead, you would feel the sensation of heading towards an unpleasant place or a place full of deadly ghosts.

Even looking at the river water below could give you a sensation as if you would drown forever if you fell into it.

Occasionally, there were sounds of owls, which when combined with the night wind, could make someone shiver in fear.

Isabel's eyes moved left and right, as if she was alert that a certain creature might jump towards them.
