Sword Logic dictates that when a being is defeated, someone must take their place. We killed Oryx, therefore we were greater beings. Oryx held power and responsibilities, and now that power should be in our hands. Succumbing to the Darkness would be in the form of taking our rightful position that we ripped from Oryx's hands. We had the courage to venture into the Darkness, but the strength to return to the Light. This is an end state allegory for when the Osmium Heirs ventured to the Deep and chose it.
