I'll give you one more clue then:
Does this Darkness have a name?
No other reference needed and no, not pop culture referenced.
English
-
<IT, the Deep, the Darkness, Phantom Ship, Ghost Ship, Phantom, Black Triangle, Pyramid, Titanomach, Flower-Eater, the Queen of Final Shapes.>
-
The IT. Oof, I’m thinking Wrinkle in Time. Then again, Rasputin loves to call the Darkness that.

Good question, but I'll give you one better: Why is Darkness??!
