Letho of Gulet, also known as the Kingslayer, is a Witcher from the School of the Viper and the main antagonist in The Witcher 2: Assassins of Kings. His closest associates are Auckes and Serrit, also Kingslayers and Witchers from the School of the Viper.
For reasons which were initially unknown, he enlisted the help of Iorveth and the Scoia'tael to aid him in his plan to kill the kings of the Northern Kingdoms. To back his claim, this man showed Iorveth a head he claims belonged to Demavend, King of Aedirn and Sovereign of the Pontar valley.
The Witcher 2: Assassins of KingsEdit
Letho is first seen in the Prologue, where he is revealed to be King Foltest's killer. In a later cutscene, he appears to have just killed King Demavend of Aedirn and comes to Iorveth's hideout seeking Scoia'tael assistance in killing Foltest.
In Chapter I, Letho attempts to betray Iorveth by trying to turn one of his lieutenants against him. However, the elf refuses and Letho kills his entire group, leaving the elf to be captured by Flotsam's guards. Geralt later brings Iorveth to Letho as a ruse to expose the latter's treachery. However, Iorveth and his Scoia'tael are attacked by the Blue Stripes, leaving Geralt and Letho to battle each other. Letho prevails in the battle with Geralt but once the witcher is down, he does not kill him. Letho explains that Geralt once saved his life, so with this small mercy they are now 'even' and leaves to kidnap Triss Merigold and force her to teleport them to Aedirn.
Geralt later learns that Letho is a Witcher of the Viper School. Geralt had first encountered him in the forests of Angren on July 25, 1270, while chasing the Wild Hunt in search of Yennefer. He had rescued Letho from death after the latter had been struck by a slyzard's tail. Letho works with two other witchers of the Viper School, Auckes and Serrit, who are the ones who attempt to assassinate King Henselt in Chapter II.
Geralt meets Letho for the final time in the Epilogue, right after the fight with Saesenthessis. The kingslayer waits for Geralt in the centre of the ruins by the Temerian Quarter. Geralt may ask about his intentions, the Wild Hunt, Yennefer and/or other major events. Geralt must then choose to either let Letho go or fight him to the death. Depending on the outcome of that choice, Letho will ultimately either leave or be killed by Geralt in their duel.
The Witcher 3: Wild HuntEdit
Letho will make an appearance if he was spared in the second game.
