Hell's second layer, hidden high above.
The silver mirror hung suspended in the air, no longer easily accessible to Mephisto.
Its 'weight' had become increasingly terrifying, and it continued to grow heavier every second. Dark serpents circled around it, ceaselessly moving through space, silently drawing in threads of gray matter, slowly and steadily increasing its volume. Despite his calm demeanor, Mephisto's body trembled unconsciously.
This was not out of fear but merely a natural instinctive reaction of life. Mephisto, having leaped several ranks from an ordinary great devil to the lord of an entire level of Hell in a short time, grew stronger, but his body had yet to transform.
Just as a native deity needed a long time to recover once their divine body was completely eradicated, it was not an easy task to form a body that matched his current powers.
