Rose is a highly successful author, having published the bestseller "Complacency of the Learned", a story which her pre-scratch self also happened to have written. She is Roxy's ancestor, and Roxy views their ancestor as a parental figure, which is why Roxy addresses her as "mom", much like how Dirk sees and looks up to his ancestor like an older brother.

It should be noted that she is described by Roxy as having possession of "Vision Omnifold", like a Seer, a direct parallel to the class of her pre-scratch self.
