Geralt's story will influence the relationships and perceptions between characters and species, as well as the borders and alliances of various kingdoms. The Witcher universe will ultimately be molded by players' choices and actions. He will assist in defending the keep against the Wild Hunt, and provide some entertaining dialogue in cutscenes. Should players choose to follow Letho and assist him, it is possible to send him to the Witchers' home of Kaer Morhen with Lambert, Eskel, and Vesemir. His fate is unknown, though it is likely he perishes in the subsequent hunt for his life. If players do not follow Letho, he is left to return to his unsatisfied employer and is pursued by hounds and bounty hunters. Geralt will spend a majority of the game hunting Letho down, or dealing with the consequences of his actions, but his final fate is left in the players' hands. Keeping true to this legacy, Letho is responsible for the murder of King Foltest and setting off the events of The Witcher 2. He hails from the School of the Viper, an order of Witchers known for their reputation of killing both monsters and humanoids. Letho the Kingslayer is one of the few fellow Witchers that players can meet in the Witcher trilogy. This is one of the most impactful decisions in the Witcher games. Saving Triss will result in Temeria being torn asunder, Roche and Anais being declared outlaws and going on the run, and the corrupt leaders of the kingdoms gaining more power.

Unfortunately, this choice will result in a witch hunt for all mages across the continent, placing Triss, Yennefer, and their colleagues in grave danger. This is the best outcome for Anais and her family, and arguably the best outcome for Temeria. There will also be an opportunity to make Temeria a protectorate of Redania, and place the country under the control of King Radovid. Rescuing Anais alongside Roche will give players the opportunity to make Anais La Valette the next Queen of Temeria and maintain its independence. While Triss is close to Geralt personally, Anais La Valette could potentially change the lives of all the subjects in Temeria. Anais La Valette is the rightful heir to the throne in Temeria and can claim her place as Queen if she is retrieved and safely delivered to Roche. She also assists him after he has lost his memory, though her intentions aren't the purest. Triss Merigold is a powerful witch and potential romance option for Geralt. Both women are extremely important to the Witcher world. In The Witcher 2, players will have the choice to save either Triss Merigold or Anais La Valette, assuming players have taken Roche's path. This can be a hidden surprise in the Witcher 3, as Roche will become available as an additional defender against the Wild Hunt at Kaer Morhen. Helping Vernon Roche in his campaign for justice will cause him to grow fonder of Geralt and eventually build a rapport with him. Geralt can determine Vernon Roche's fate throughout a myriad of choices in Witcher 2's campaign, all of which contribute towards Roche's survival and his trust of Witchers as a whole. Related: The Witcher Game's Original Concept Didn't Include Geralt This choice will change Witcher 3: Wild Hunt and Geralt's available allies and connections. A staunch supporter of King Foltest, Roche searches desperately for his leader's killer and begins to stage a conspiracy against King Henselt following the execution of his Blue Stripes. Unlike many characters of prestige in the Witcher series, Roche came from poverty and worked his way through society thanks to a stunning military career.

Vernon Roche is a character that appears frequently throughout Witcher 2, and is the Commander of a special forces unit in the Temerian military known as the Blue Stripes.
