To save the past while the future crumbles

"What grandiose names…" Vaner muttered while retracting his hand from the wall. 

"Authorization I can understand. Corporation likely is an archaic word for cooperation… But Sigma? Technical maintenance?"

Vaner shook his head. 

"No, I won't get anywhere with just guesses. I can't mix those words either," he told himself as he took a step back from the entrance and sat down, staring at the plaque he could see and the parts of the wall that invoked the words despite its runes being long lost to the decay. 

"Technical Maintenance Shaft…" Vaner muttered, staring at the only place with the runes left. 

"Shaft… Is this some sort of an ancient joke?" he thought, grasping at the straws. "If it's the shaft, then there should be a shroom and balls somewhere!" 

Vaner shook his head to the side, hoping to see some clues in his surroundings.
