Kitako: Only one thing is not yet clear to me. Why the Wild Hunt was specifically looking for Geralt and Yennefer? Even Letho ask this to Geralt, which he replies something like "I have an idea about that but won't tell to you".
Khasim83: The King wants to use Geralt and Yennefer to lure Ciri and force her to give birth to his child. He already tried that in the Saga, but failed because he was very old, even for an elf, and he found Ciri very ugly (mostly because of the scar on her face), therefore he couldn't "finish the job".
BIG SPOILER ALERT:
The King of the Wild Hunt (Eredin Bréacc Glas) is not Erl King (Auberon Muircetach). The last one is already dead. But yes, he wants to find her for the same reason.
deathcoy: Lol, Nilfgarian Emperor wants to copulate with her(damn incest perv), the Wild Hunt too, man shes a popular breeding choice. But they made a mistake of messing with Geralt's Surprise Child...
Khasim83: I doubt the Emperor wants to copulate with her since she's his daughter...
He even married a fake Ciri that he wanted to replace later with a real one. It's all because of some prophesy that states that her child will rule half of the world.
