With a Conquering Air (слэш)

From the kinkmeme: AU Warlord!Geralt receives Tribute!Jaskier as a sacrifice to appease him in every way possible. Jaskier has no choice on the matter and he’s fully aware of the awful rumours that have spread about Geralt and his ruthless conquests. (But we all know those aren’t legit.) A classic angst with a happy ending please! A dash of smut to heal those scars and a sprinkle of new found love!
Jaskier arrives at Kaer Morhen knowing his family gave him up without a second thought, and absolutely sure that the dreaded Warlord of the North will value him even less than his own blood did. But the White Wolf and his pack are not what Jaskier expected...and if he's unreasonably lucky, Kaer Morhen might become far more of a home than Lettenhove ever was.
...He is, in fact, going to be unreasonably lucky, because the Warlord of the North is a far finer monarch - and a far better man - than Redania's king has ever dreamed of being.
