Polluted Land, the frontier observation point.
Two fully armored Devil Knights trekked through the muddy soil.
Each of them held a wand in their hands that did not match the style of their gear. At the top of the "wand" was a grey-white crystal, which darkened as they moved deeper.
When the color of the crystal turned to dark gray, they stopped and looked around.
The surrounding fog was thick, with white mist floating particles of unknown substance.
"This is the limit," one of the Devil Knights said to the other, "Captain, if we go any deeper, our protective gear won't be able to handle the pollution levels; we need a purifier, or..."
Yuri, the captain of the Devil's Army, raised his hand to his subordinate Knight, signaling him to stop talking. He then tapped his neck and a muffled voice came from under the mask: "Check if the emergency device is intact."
The Knight nodded and began to check the emergency device under the mask.
