Legolas and Captain Stokes did not leave the headquarters in a high-profile manner. Due to the fear of more spies potentially being left in the headquarters of the Hunter Union, they kept their movements as elusive as possible.
With General Toothpick's help, none of the thousands of hunters that roamed the massive headquarters of the Hunter Union detected their movements.
Legolas left with his student and the players.
As for Captain Stokes, he and his hunters left in batches.
As the strongest base of the Clown Society that was in the Dragon Shelter, Legolas dared not underestimate Raging Tempest's lair.
To increase their chances of success, he pulled all trump cards available to him. While the hunters left in batches, secretly, a group of other hunters disguised as merchants also left with transport carts carrying weapons.
To reduce the chances of attracting more suspicion, Legolas ordered 3 of the hunters in Captain Stokes' original squad to remain behind in the headquarters.
