Comments of chapter undefined of Odyssey of the Blind God

My theory: 1) Damian infected the Night Shadow elfs as revenge, getting them exiled, thus Nail has more enemies. 2) Damian took ik the Night Shadow elfs after they got exiled, and granted them power, thus Nail has more allies. Theory 2 is probebly more likely. Either way the Night Shadow elfs atleast have a connection to Damian.
