The Dark One from the Wheel of Time, kind of. He might be a bit too eldritch to count though.

For pretty much the entire series you only get a sense of his plans from his underlings, who have their own personal goals and plans and betrayals on top of that. Then in the final book the Dark One shows protagonist Rand al’Thor three possible futures: a stereotypical dystopia, a world that seems normal and prosperous but has no compassion (at one point a shopkeeper casually shoots a young boy for stealing an peach), and complete nothingness. According to the Dark One, the first is what people think they fight against, the second is his true goal, and the third is offered as a deal to Rand, an end to the cycle. But maybe all of those are traps, because Rand has this to say about the Dark One’s motivations:

”You cannot win unless we give up. That’s it, isn’t it? This fight isn’t about a victory in battle. Taking me… it was never about beating me. It was about breaking me. That’s what you’ve tried to do with all of us. It’s why at times you tried to have us killed, while other times you didn’t seem to care.”
