As Zatiel enters the Fiend Essence Extract Chamber, with the Angelic Paragon at hand, he saw five people already inside.
Four of them were Sophia, Ezequiel, Rax, and Kilo. Each of them had a tentacle made of pure Abyss Aura connect to their hearts. In front of them was a big pile of unconscious people of the Heavenly race and behind, a pile was also forming, but the ones in that were dead.
Under Zatiel's instructions, they were using the chamber to increase their energy pool and also using the Heaven Swallowing rune to absorb the energy on those Rank 1 Angels and use it to advance the completion of their Elemental Bloodline Marrow.
Since the Heavenly race already knows about them and the fact they capture a great number of their people as they created the towers, Zatiel was free to use them.
