Of His Blood and Bone

Of His Blood and Bone is a main quest in The Witcher 2: Assassins of Kings, set in Chapter 3 at Loc Muinne. Geralt and Vernon Roche break into the heavily guarded Kaedweni camp to rescue Anais La Valette, the kidnapped daughter of King Foltest. Because Roche is Geralt’s partner, the quest belongs to the Roche path.

The two split up to fight their way through crossbowmen and footmen, then push towards the basement under the library where the sorcerer Dethmold is staying. Dethmold’s veteran mercenaries and his young apprentice, who seals the basement with a magical barrier, stand in the way. Dethmold, hidden inside a dome of magical silence, is caught unaware and killed by Roche, which brings down the barrier around Anais.

Roche must then decide who gets the girl. He either keeps his promise and hands her to King Radovid of Redania or takes her to the Temerians. In both cases Geralt escorts Anais and Roche to their destination and then leaves them at the gate to finish his own business.

Quest Consequences & Choices

Anais can be given to King Radovid or to the Temerian interrex John Natalis. If she goes to Redania, knights of the Order sent by Radovid escort the group to the king’s quarters. If Roche refuses to give her up, the Order’s knights block the way outside the library: either a fight breaks out and the group cuts its way to the Temerian camp, or Siegfried of Denesle lets Geralt, Roche and Anais leave in peace. The journal notes that the consequences of this decision were not yet understood at the time.
