I'm looking for help remembering things about the book series.
From what I remember in The Gunslinger Roland originally is chasing the Man in Black to get revenge for what he did to Rolands mother. Correct? The Dark Tower is mentioned but it isn't until the end of the first book we learn his real purpose is to climb the tower. During Wizard and Glass Roland sees in the Grapefruit that the Tower is in fact real and that's where his journey starts for the tower? Is that right or did I get things wrong?
