What did rose see in the cueball(or what its called, the thing where you can see answers and what Doc Scratch was prototyped from) that made her grimdark? And didnt Vriskas ancestor have it first?
There are multiple cue balls that have been dispersed by Doc Scratch. She asked the cue ball whether the Horrorterrors were benevolent and this caused her to go grimdark. What she saw wasn’t shown but the answer was obvious: they’re not.
I think that whether or not the horrorterrors are benevolent is up to the reader. You could argue they aren’t by saying they took over Rose and corrupted her. You could also argue that they are as they gave Rose excessive amounts of power so that she could seek revenge on Bec Noir for killing her Mom.
It’s entirely debatable.
