Leon spoke of a method to enter the Cold Valley of Yilushier, which involved obtaining a specific item.
That is, the "Little Puppet" given to a church-dressed figure by the Cold Valley force seen in the image after defeating Overlord Vonier.

"Captain, why didn't we notice this message when we first came here?"
Berto from the Skyrim Strategy Group stared at the conspicuous advice on the ground and asked.

For a moment, she doubted whether her eyes were real.
"I guess I've really been too exhausted lately..."
Indeed, the means to enter Yilushier was inscribed as advice on the bridge from the start.
