All these years after release and The Witcher 3 still hides some secrets but it appears that a big one, at least in regards to the story, has been unveiled.
Massive and detailed games often hide secrets so well that it takes internet sleuths years to uncover them but The Witcher 3 took it a few steps further. First, there were hints about the narrative of an endearing character in Blood and Wine, which led to the discovery of their fate , beyond what we could see in the ending slides.
It was followed up by a more recent tease from devs about the fate of another beloved character, this time involved in more than just the expansion. Ciri, Geralt and Yennefer's adoptive daughter, was previously believed to have perished, should the player achieve the worst ending.
This doesn't appear to be the case and due to the nature of the subject, we have to warn you of major story spoilers ahead. If you intend to play The Witcher 3 and haven't done so before, we would urge you to do it before continuing with the latest secret.
Upon getting the worst ending, Ciri teleports to prevent the White Frost and is presumed to have died during the effort. Meanwhile, Geralt goes into depression and takes it out on the last Crone of the Crookback Bog.
The new revelation that was hinted at by the developers is that Ciri doesn't actually die while stopping the apocalyptic event. This was found out after Geralt revisited the last Crone and found a tapestry she was weaving. It was about the tower where Geralt thought he had seen the last of Ciri but it showed a bird flying away, hinting that she successfully evaded her demise.
In the end, it was a secret that didn't actually impact that many players since most never actually finished the game while the rest were likely to just get one ending, a pretty big chunk of them seeing Ciri off in a different direction.
