Chapter 954: Soul Overcrowding. 2
"Aye, Ma'am." Nyx looked to where the conflict was occurring, and they saw the metal golems attacking Hela's Army of Darkness.
With their Draconic Eyes, everyone present saw what happened when soldiers from both sides died. In the case of Hela's Army of Darkness, tainted black Souls would emerge from the fallen and fly back somewhere.
The same happened with the metal golems, indicating that they were not just lifeless golems.
"Nyx, you can see it, right? Follow the Souls, find out where they're going," Scathach ordered.
"Okay." Nyx's wings opened, and she flew towards the Souls.
Everyone observed that each time one of them 'died,' the Souls from both sides would ascend to the sky. In the case of Hela's tainted Souls, they would return to her staff, and then a new Being would be created, essentially forming an immortal army.
