has finally been announced after almost ten years without a new game in the series, and Ciri has been shown taking center stage with the new title. As with any title as hyped-up as, there are a plethora of questions surrounding it, such as what the plot will be about, whether legacy characters like Geralt will make a return, and Ciri got into the situation she's in at the start of the reveal trailer.
