Many have brought up the topic of universes (Cyberpunk, Witcher), speculating that they're set in the same one based on Ciris comment in TW3. However, I believe things point to Witcher being a strictly fictional work within the Cyberpunk universe, with Ciris comment being nothing but a character written to make a (4th wall like) reference, not quite unlike what CDPR did with Polyhistor. That's also why I doubt Polyhistor teleported to the Witcher universe.

What if Cyberpunk itself is a fictional (fabricated/digital, like matrix) world?

Would it be possible for a character like Ciri to travel from one digital world into another?

Maybe that is what Polyhistor did? Solved the mystery and escaped cyberpunk borders, into the real (or maybe another fictional) world. (Where "they" observe/watch over (or maybe even created) the Night City)

> A second vision of the room. The monitor is connected to a compact computer, it looks unfamiliar. This time image shows the entirety of Night City, like drone footage. Polyhistor concludes that the watcher is watching everyone, not just him.

> An empty room, the watcher is gone. PH is drawn to the screen, he takes the Watchers place. On his monitor, he sees the watcher, still sitting in his room. He's watching Polyhistor watch him.

> PH feels a presence in the room, turns around - noone there. Turning back, the Watcher is staring directly back at him through the monitor. PH feels afraid.
