Shard attempted to lift the Black Metal Balance to inspect it, while the boy, who hadn't dared to speak, cautiously supported Mrs. Miles and said:
"Maybe we can determine the direction by observing the height difference between the two sides... just like a compass."
The boy was right. The Balance was not in a state of equilibrium. As he held it and rotated in place, the left end of the Balance was always pressing down, and the degree of depression varied depending on the direction it pointed.
So Shard turned in place and found the direction of the lowest depression of the Balance. It pointed to the left front. Thus, the group held up torches and walked a few dozen steps along the paths between the stalls, leading them completely into the Black Mist Camp. During this, the Witch allowed the Balance to float from Shard's hand and allowed it to spin slowly, to help the group better adjust their direction.
