Pathfinder Adventure Card Game

I defeated a villain, searched the location, and didn't find any more villains. Now what?

The location’s When Closed effect happens: First, apply any effects that say “before closing.” Then banish all of the cards from the location; it is now closed. Finally, apply any effects that say “on closing” and put the location card back into the vault. The location is no longer in play, and all characters that were at that location always immediately move. After the encounter, the exploring character may no longer explore.
