As Corey and Divine phased through the wall, leaving the manager's office behind, they found themselves once again in the labyrinthine corridors of the Underworld Emporium. Divine's Vanishing Ring concealed them, allowing them to move undetected.
As they walked to the stairs leading to the top most part of the Emporium, Divine, with a hint of relief in his voice, whispered through their telepathic link, [Good call on leaving the map. It's too risky, and we've already pushed our luck in here.]
After leaving the office of the manager of the Emporium, Divine had thought about his actions and plans regarding the map. He realized that his thoughts on how easy it should have been for him to take the map could be considered foolish.
The map was undoubtedly one of the, if not the most precious object in the Underworld. And there was no way the manager, who was a key existence of the Underworld would not have employed certain measures to make sure the map would not be taken no matter what.
