After Chapter II (Roche)

In this chapterGeralt must choose whom to rescue: Triss or Philippa on the Iorveth path, or Triss or Princess Anais on the Roche path.

Loc Muinne is the stage for the mage conclave, a gathering that could end persecution or consolidate power. Philippa and Síle use it to take control through Saskia, whom they plan to unleash as a dragon. Letho's actions in the background complicate the plan.

Geralt must choose among captives and allies. Whom he rescues determines whether the mages can restore order after the crisis. In the final confrontation, he can kill Saskia, spare her or break the spell holding her.

The decision at Loc Muinne is the main hinge of the game. Saving Triss keeps the Conclave together and prevents a pogrom; saving someone else may be the human choice but has political costs. The game does not hide that every option abandons someone.

Síle de Tansarville's fate is a character study. She is ambitious and cruel, and the way she is trapped by Letho's sabotage forces Geralt to choose whether even enemies deserve rescue. It is a smaller version of the main question of the series.

Saskia's last scene is the emotional peak. A dragon who was used as a weapon can be killed, spared or freed. Whichever choice Geralt makes, the cost is clear: he cannot undo the damage that others inflicted on her.

In this chapterGeralt finally confronts Letho, who reveals Nilfgaard's plan to destabilise the Northern Kingdoms through the assassinations.

After Loc Muinne the consequences arrive. If Geralt saved Triss, the mages reorganise; if not, the North descends into violence against sorcerers. Geralt then tracks Letho down and demands the truth.

Letho explains that the Kingslayers were Nilfgaard's tools, used to remove kings and break the North's alliance. Geralt can fight him or let him go. The final scene shows Nilfgaard's armies crossing the border and starting the war that dominates the next game.

Letho is the best antagonist of the early saga because he is not a monster. He believes his actions protect witchers from extinction and cannot see himself as a villain, which echoes the way Geralt justifies his own neutrality.

The reveal that Nilfgaard planned the assassinations turns the game into a prologue for a world war. The player's decisions about Roche, Iorveth and Henselt now determine who will face the invasion. As an ending, it is open on purpose. The war is no longer a rumour, the Continent is fragmented, and Geralt's search for Ciri is the next step.
