“The core of Anakin that resides in Vader grasps that Tatooine is the source of nearly everything that causes him pain. Vader will never set foot on Tatooine, if only out of fear of reawakening Anakin.”
― James Luceno, Star Wars: Dark Lord - The Rise of Darth Vader

“Aboard the Executor, Vader considered his upcoming meeting with Luke. Since last they’d met, the boy had had time to come to terms with what he’d been told. On some level, he must know the truth, that Vader was his father. Of course, that had been in another lifetime, when Vader had still been Anakin Skywalker, but the fact of it remained.
He would turn him. He knew he could, because he had felt the dark side rise in Luke, had felt the power of his anger. The boy had loosed it once; he could be made to free it again. Each repetition became easier. The dark side was a path that grew wider and deeper each time you trod upon it. Soon it would be no effort at all for Luke to allow the dark side to rule.
And the Emperor was right. Luke had much power in him. It was raw, unchanneled and untrained, but it was vast. His potential was larger than the Emperor’s, larger than Vader’s.
But it was still only potential and not focused energy. When next they met, Vader would still be more adept, still the master. He would defeat the boy and bring him to the dark side. They would be in accord, father and son.
And when that happened, nothing in the galaxy could stop them. None would dare oppose them. All would bow before them. Worlds would tremble at their approach.
Under his mask, Vader smiled.”

“SITTING NAKED in his chamber and working on his healing meditation, Darth Vader frowned. There was a disturbance in the Force. He reached for it with the power of the dark side…
He could not connect with it, whatever it was.
Abruptly the sensation of a ripple passed.
The dark side still had surprises for him. Like a fire, it could warm or burn, and great care must be taken not to trip and fall into it. He had seen what extensive use had done to the Emperor; it had eaten away at him physically. But that would not happen to Vader, for he intended to master the dark side. He was well on the way. It would be only a matter of how long, of when, not if. And when he finally snared Luke, the process would go faster. Two powerful magnets would attract more of the dark energy than one. Together they would manipulate the Force quicker than either could alone.
So strong, the boy. Who could have known? Luke Skywalker—his son—might well be the most powerful man in the galaxy.
He allowed himself a smile, even though the expression stretched scar tissue and was painful. He could withstand pain.
He was the Dark Lord of the Sith, and he could withstand anything.”
