Nightmare of Dominus Ghaul

"The Red War saw so many lives lost. Saw the Light taken away so easily. In Light, there is only weakness."

- The Darkness to the Guardian, upon banishing the Nightmare of Ghaul

The Nightmare of Dominus Ghaul is a Nightmare of Ghaul that appears in Shadowkeep. Like all Nightmares, it is a manifestation of the Guardian's fears and trauma generated by the Darkness, and is used by the Darkness to taunt the Guardian by reminding them how easily the Light was taken from them.
