A wormwhole

A week later after the disappearance of the Uno Labyrinth, in the Frontline, inside the 3-star chief office, 3-star Chief Dix Marcel was busily working in front of his desk when the door suddenly pushed open.

He paused his work and looked at the person who came inside. 

"Sir, here is the partial report from the team we sent to assist the researchers." His subordinate came inside and handed him an envelope.

With squinted eyes, the chief nodded and took the envelope. Then he took and read the document inside. 

Stated in the report was the summary of their activities.

It stated that the group decided to make a temporary encampment near the vanished entrance to study further the reason for its disappearance, or any unusual phenomena. 

Aside from that, there was also the report about their search around the area for any unusual changes and the expected increase in the number of hostile creatures around.
