A load of thralls and shriekers inside an enclosed dark place with no high ground. Just merely flat ground. To make it worse, all you have is a hand cannon at your disposal
Ourselves
Rn pur character doesn't know what the entity behind the darkness looks like. Only time our character has actually been face to face with them they showed themselves in the form of the character.
I think I we had to fight our own nightmare it would be ourself because of that. And likely because we don't know what powers the entity behind the darkness has the nightmare would either use the same abilities we have, with a obvious darkness flair to them.
Or abilities that we associate with darkness forces, like a mix of scorn and hive abilities using soup fire and dark ether kinda stuff
For those who watched it think like instead of our solar the nightmare would have the same ability but it would be the same kind of flame desthstorm has from the flash. Black and blue instead of white and red/orange
Reflect on what our Guardian slew these past 8 years.
It’s the form The Witness took when during our conversation inside the Lunar Pyramid.
[spoiler]Our Nightmare, our greatest fear, is ourselves. It’s what we could become if we lose ourselves to temptation and power.[/spoiler]
The Witness really knows how to push people’s buttons.
A Super Extra Quantum Horse of course.
That thing is a nightmare by itself.
It is what writers come up with when they have writers block AND a deadline.
