A Bird's Eye View & Deathly Afraid of Heights

Lee Seng and David ascended the stairwell. The echoes of their feet hitting each step traveled throughout the stairwell. David kept up with Lee Seng despite his looks. Lee Seng noticed occasional odd glances from David as they climbed. Lee Seng donned the Fox mask and kept the Dark Matter suit on, which David soon fixated his eyes on.

"S-so what's this black-gray gunk wrapped on your body?" David asked out of curiosity. 

"Dark Matter," Lee Seng replied. David began to open his mouth to ask what it was but Lee Seng continued. "It's a by-product of the Biohuman serum which was introduced twenty five years ago. It basically gave us powers through usage over Dark Matter."

"So why do you have that Dark Matter wrapped all around you?" David asked as they rounded the corner, climbing another set of stairs. Lee Seng didn't answer right away. His silence only made David understand that even Lee Seng had secrets he didn't want to share.
