Chapter 476 - Umbra wants to capture Nidhogg.

Umbra stood still for a few seconds at the entrance to the ancient containment chamber, silently observing the scene before her. Even for someone who ruled the Umbral, someone accustomed to dealing with impossible creatures, ancient entities, and calamities that existed since before mortal history, this was still… problematic. The entire hall was in ruins. What had once been a carefully constructed prison, reinforced with ancient magic and chains forged to contain something that shouldn't even exist, now looked more like the remains of a forgotten battlefield. Black walls were cracked in multiple directions, pillars had been broken as if made of glass, and the floor was marked by irregular craters, as if something colossal had struggled within with almost primal violence.
