Allied with Iorveth at the end of the first Witcher 2 act, we left Vergen after all quests have been completed, and traveled towards Loc Muinne, the final city we must visit in our journey.
The third Witcher 2 act continues some quests started in the previous chapters and also allows us to complete new quests, thus you will be able to earn even more experience points and reach new levels.
Many side-quests and main-quests started earlier in the game will end in Loc Muinne, and the choices made so far, will affect the games ending; however the final goals remain unchanged.
Geralts main task is to find Triss Merigold and Letho, Henselts assassin.
At the end of the second act, Geralt and Iorveth realized that Saskia is mind-controlled by Philippa, who took her to Loc Muinne.
Your journey begins in the mountains near Loc Muinne, and the first quest activated when you reach this area is called For A Higher Cause!
For each Witcher 2 quest, an independent walkthrough was created; explaining how to complete your goals, and how to earn the corresponding rewards.
When you begin the third chapter of the game (sided with Iorveth), The Assassins of Kings and Where is Triss Merigold (two of the quests started earlier in the game), will update.
After a short cutscene,and a dialogue with Iorveth, For A Higher Cause! will be added to your journal.
