Ciri pulled Geralt aside for a confidential heart-to-heart. She confided to him that Avallac'h had a hidden lair, a secret place that not even Ciri, his star pupil and long-time traveling companion, had been allowed to visit. Intrigued, Geralt decided to enter this secret lair and find out what the Seer was hiding.
The most important part of any conspiracy is for the co-conspirators to trust each other fully, and Ciri's revelation had cast a shadow of suspicion on Avallac'h. Geralt knew light must be shed on this shadow before it proved too late.
It turned out Avallac'h's well-guarded secret was a hidden laboratory in which he carried out research on Lara Dorren's gene - the gene Ciri bore within her, the cause of her power and her misfortune. Ciri was understandably less than thrilled to see herself through Avallac'h's eyes as a subject in some twisted experiment.
Meanwhile, they also discovered this secret research wasn't the only reason the Seer kept the place hidden. Avallac'h seemed to have been using it as a pleasure alcove for trysts with his elven lover. Who would have thought? It turns out even the wisest of sages is not always driven by pure reason alone.
