At the entrance to the Lost Realm instance, layer upon layer of barricades isolated the instance's entry from the surrounding areas. Even though Jeremy had been brought here by General Howard's adjutant, he still did not have the clearance to approach the instance's entrance directly.
The adjutant showed the soldiers guarding the area the pass he carried. Only then did the soldiers open the gate leading to the entrance of the Lost Realm instance.
"You've gone to such great lengths to seal off the instance entrance. It seems the Lost Realm instance really poses a significant threat to you," Jeremy remarked upon seeing the scene.
