For the Advancement of Learning is a secondary quest, that begins immediately after A Favor for a Friend. Geralt sails to Fyke Isle in search of Keira and notices the lit at the top of the tower is on.
As he approaches the tower, Keira exits the structure, pocketing Alexander's notes on the Catriona plague. She admits that she is planning to use the notes to bargin with Radovid, so he could pardon her for her association with the Lodge. Depending on the dialogue, Geralt can either let her take her chances with Radovid, kill her to prevent the notes from being used to create a biological weapon, or convince Keira go to Kaer Morhen.
- Geralt kills her: If Geralt tries to forcefully stop Keira, she will fight to the death.
- Keira goes to Radovid: If Geralt allows Keira to attempt to parley with Radovid, she sadly discovers that Radovid has no interest in bargainings and has her executed via impalement. Geralt and Triss recover her body during A Final Kindness.
- Keira goes to Kaer Morhen: If Geralt convinces her to go to the witcher fortress, she will assist in fighting the Wild Hunt to protect Ciri. She saves Lambert during the fight, and after the battle, she and Lambert go off on their travels together, where she will discover the cure for Catriona in the future, even if she gave Alexander's notes to Geralt.
Journal entry Edit
- Nothing about sorceresses should be taken at face value. Their faces least of all - those perfect, ever youthful visages have as little to do with nature as Hierarch Hemmelfart has with charity. If anyone should have learned to think twice when dealing with them, it was Geralt, and yet still he accepted Keira's dinner invitation.
- During what Geralt naively thought to be innocent conversation between friends, Keira tricked him into revealing information about the mage Alexander's laboratory and then, when he was least expecting it, sent him to sleep with a spell so he could not stop her from carrying out her nefarious plans...
If Geralt convinces Keira to go to Kaer Morhen:
- Geralt caught Keira red-handed as she was leaving the tower with the results of Alexander's research on the Catriona plague. She was convinced these notes could be used to find a cure for this decimating disease. What's more, she hoped that the prospect of obtaining such a cure would convince King Radovid to let bygones be bygones and host Keira at his court. I doubt Radovid would have proven so broad-minded - luckily, Geralt convinced Keira to abandon these foolish hopes and give Oxenfurt a miss, seeking shelter at Kaer Morhen instead.
If Geralt lets Keira go off to see Radovid:
- Geralt caught Keira red-handed as she was leaving the tower with the results of Alexander's research on the Catriona plague. Although he feared the sorceress would use these notes for nefarious purposes, Geralt decided to let her go. Whether it was because he ultimately believed her assurances that no one would suffer as a result of her actions, or because he wanted to avoid a potentially bloody conflict - difficult to tell. Geralt is a man of many secrets, including ones he keeps even from me.
