Comment and tell us your allegiance to which of the five Sinners.

As we all know the Abyss was brought in teyvat by Nibelung during the war of funerary flames. Before that there was no Abyss in teyvat as far as we know meaning there shouldn't be any other source of abyss in teyvat.

During the Cataclysm King Irmin let the abyss sibling absorb an unlimited amount of abyssal energy in a deep secret underground area of Khaenri'ah it was later implied that this absored abyssal energy become the source of sinners powers. In Norse mythology, Nibelung resides in the deepest layer of the world. Based on this i theorize that after Phanes defeated or destroyed Nibelung they sealed their body in the deepest layer of Teyvat. King Irmin may then have led the abyss Sibling there allowing them to absorb it which later became the source of the Sinners powers.
