Primary quest

Defending Kaer Morhen is the very first quest of the game and it spans the entirety of the Prologue. It is the game tutorial. In this quest, our hero learns (or re-learns) to use a Σπαθί, fight bad guys both big and small, not to mention groups of them, cast signs, brew potions and skin monsters. He learns the basics of what he can do and gets a taste for what he could do. All this as he and his fellow witchers try to fend off an attack on the keep by the nefarious Salamandra organization.


After being found, unconscious in the woods outside Kaer Morhen, Γκέραλτ is taken back to the fortress and nursed back to health. The witcher is just beginning to get his bearings when the fortress is attacked by a bloodthirsty gang led by at least one mage and a notorious outlaw known only as the "Professor". We learn that this wanted criminal has promised 50 oren(s) for every witcher killed, so his hired crew is quite keen on getting a bit of extra cash.

Lambert is the first to notice that something is wrong. He cautiously makes his way to the main gate of the keep where he is met by the first wave of the attack. He fends off several of the would-be invaders, but realizing that there are quite a few more, he retreats to warn the other witchers of the coming attack, but the gang is hot on his heals.

Realizing immediate danger, Vesemir assesses the situation and takes charge. It is all hands to the deck! He presses Γκέραλτ into service, telling him to simply grab a sword from one of the training forms and help fend off the assault. The witchers, with the help of Triss, manage to hold off the onslaught long enough to reach the gate to the upper courtyard, but they need to make it to the inner courtyard and that gate is currently closed.

Vesemir orders Γκέραλτ to get to the winch and open the gate by using the back way through the tower. Our hero is initially hesitant, but gets on with the task. He is immediately set upon by numerous other bandits as he races toward his destination. Reaching the tower, he stops short just in time to avoid falling into the gaping pit which has replaced a large portion for the former battlement. The stairs still seem more or less intact and having no real alternative, he runs up.

Apparently the stairs were less solid than they initially appeared, and the structure begins to give way beneath the witcher's feet. His instincts kick in and he makes a heroic leap, barely reaching the landing. His pursuers are not so lucky and several fall to their death. Those who do not are left to curse Γκέραλτ from below as he continues on his mission to open the gate.

A few more bandits attempt to stop him, but Γκέραλτ finally reaches the winch allowing his beleaguered allies to enter the inner courtyard. Triss then collapses the entrance to keep their attackers out, allowing for a short breather in the fighting. This is the first opportunity that anyone has to discuss what has just happened.

Apparently the Professor has killed at least 17 people and is wanted in several kingdoms. Triss has heard of the mage, Savolla, but does not have very much information other than the fact that he is mad.

On Vesimir's orders, Leo and Γκέραλτ run back to the lab only to see it being ransacked by the Professor and the mage, but since there is a magical barrier in the way, they can do nothing but watch helplessly. They also can not get out of the underground because the mage has rather inconveniently collapse the tunnel leading to the stairs out.

Then Leo suggests that Γκέραλτ clear the side passage so that they can get out of the underground and advise the others of what has happened. Leo explains that he can not clear it himself because he broke his hand training and can not form the Σύμβολο του Αρντ. Worse still, Γκέραλτ can not remember the Σύμβολο του Αρντ, so Leo proposes they go to the Κύκλος των Στοιχείων and see if that jogs the witcher's memory. Thankfully, it does, so they return and Γκέραλτ clears the passage to the main keep.

At this point, Γκέραλτ must decide whether he will be helping Triss save the lab, or Vesemir and the other witchers fight the frightener.

Triss: Triss, Leo and Γκέραλτ go head inside the keep. Γκέραλτ takes on and kills Savolla. Triss goes on ahead to try to save the lab. Leo and Γκέραλτ catch up to Triss who is wounded and advises them that the Professor and an even more powerful mage are in the lab, or
Vesemir: Γκέραλτ and the other witchers take on the frightener and kill it. Triss then teleports in, wounded and advises them that the Professor and an even more powerful mage are in the lab.

Meanwhile the mage has already escaped through a magic portal with the witchers' secrets, leaving the Professor behind to "clean up". Some typical bad guy posturing and then Γκέραλτ sets out to kill the Professor, but so does Leo, and less expertly so. The Professor spies his opportunity and fells Leo with a single shot from his crossbow. He then makes his own exit through that magic portal (which collapses hereafter), leaving Γκέραλτ to tend to the dying young man.

As nothing can be done for Leo, Vesemir sends Γκέραλτ to help Lambert make a potion to help Triss. Once Triss is well, she and the witchers bid farewell to Leo with a funeral pyre and set off in different directions to try to track down Leo's murderers and bring them to justice and hopefully recover the stolen witchers' secrets in the process.



Sapphire Siding with Triss: Γκέραλτ finds a sapphire on Savolla's corpse. Later, in Chapter I at the Merchants' bridge, he faces the Salamandra only, no Armored hound. This means that only two pieces of red meteorite ore and one blue can be used to forge a new sword at the end of Chapter I, but siding with Triss seems to net a greater XP reward (Quest + Kill XP) than siding with Vesemir (though I can not find any evidence of this in the quest file). Killing Savolla is worth 390 XP.
Red meteorite Siding with Vesemir: After the fight with the frightener, Vesemir gives Γκέραλτ a piece of red meteorite ore, which enables the forging of a three-red-meteorite sword at the end of Chapter I, which is the best damage-dealing sword of the meteorite swords. Also in Chapter I, at the Merchants' bridge, the witcher faces an Armored hound, in addition to the Salamandra. Killing the Frightener is worth 390 XP, but this is difficult, as you need to make the bell and cauldrons resonate and then be in time to deal the death blow while all the other witchers are also attacking it. It is easier if you do not kill any Salamandra and let them distract the other witchers instead. Be prepared to load the autosave with the choice several times if you want the XP from this path.


A Sword[]

I must remove the sword from the training form. I need the sword that's in the training form.

The First Sword[]

I need to help the witchers kill the bandits! I need to attack the bandits!

Assault on Kaer Morhen[]

The other witchers and I managed to kill the bandits. Though I lost my memory, I'm certain of one thing: the bandits were after me and my friends. I should follow Vesemir, the oldest and wisest of us all. I should follow the witchers.

The Gate is Shut![]

The bandits have closed the gate to the Upper Courtyard. We are cut off from the keep. I need to lift the gate. Vesemir suggested that I follow the fortress walls to the tower. I must get to the courtyard, climb the stairs and run along the top of the wall to the tower. When I arrive in the Upper Courtyard, I can try to open the gate from inside.

Opening the Gate[]

I disposed of the bandits guarding the gate. Now I need to open it. I must open the gate.

Preparing to Fight[]

We're safe for now. Vesemir told me to drink the potion he gave me and to check the fortress interior. I must drink the Thunderbolt potion and explore the fortress interior.

A Potion[]

I drank the Thunderbolt potion. Now I need to enter the fortress and find the underground laboratory. I should pass through the main hall before descending the stairs. I drank the Thunderbolt potion. Now I need to enter the fortress and go to the underground laboratory.

The Σύμβολο του Αρντ[]

One of the bandits is a mage. He cut off our way out. Leo will lead me to the Κύκλος των Στοιχείων, where I can learn the Σύμβολο του Αρντ, a telekinetic spell that will help me clear the exit. I must follow Leo and learn the Σύμβολο του Αρντ.

The Κύκλος των Στοιχείων[]

I learned a Sign called the Aard. I can use it to remove the stones blocking the passage. I should use the Σύμβολο του Αρντ on the stones blocking the exit.

Moving Inside Kaer Morhen or The Courtyard[]


Moving Inside Kaer Morhen[]

Triss and Vesemir argued, and I backed the sorceress — we should defend the laboratory. We ran inside Kaer Morhen to see what was happening. I should see what's happening inside Kaer Morhen. (2000 XP) or


The Courtyard[]

I must kill the frightener in the courtyard. It's susceptible to sound... Those bells and siege cauldrons should produce some noise if I target them with the Σύμβολο του Αρντ. I must slay the frightener in the courtyard. I can use sound to kill it. (2000 XP)

To the Laboratory! + Triss Wounded or To the Laboratory![]


To the Laboratory![]

I killed Savolla. Now I need to get to the laboratory. I must run to the lab.

Triss clearly lost the fight. I found her, heavily wounded, near the entrance to the laboratory. I must stop the intruders alone. Triss couldn't stop the intruders. I must descend the stairs to the lab. or


To the Laboratory![]

I killed the frightener. I must run to the laboratory, see how Triss and Eskel dealt with the intruders. I killed the frightener. I must get to the laboratory.

Leo's Death[]

Leo perished at the hand of the Professor, the bandits' leader. I need to rest and then explore the fortress. I should make sure Triss and the other witchers are all right. Any surviving intruders — well, I'll make them regret Leo's murder. I must explore the fortress, make sure the others are allright!

Talking to Triss + Revenge or Revenge[]

Leo's funeral pyre

Talking to Triss[]

Triss had a lot to say... Leo's funeral will be soon. I should talk to Triss again, or to Vesemir... I should speak with either Triss or Vesemir and then go to Leo's funeral.


The bandits who attacked Kaer Morhen shouted the word "Salamandra" — probably the name of their organization. I won't let Salamandra get away with attacking the witchers. I'm a witcher myself. I'll avenge Leo's death and recover the secrets stolen from Kaer Morhen. I aim to avenge Leo's death and punish those thieves called Salamanders, who stole the witchers' secrets. (4000 XP) or
