Throne of Thorns is earned by pushing your Infamy in Vale Sangora to its peak, level 9. It mostly comes from main story progress against Brencis's lieutenants.
AmbrusAmbrus is the youngest of Brencis's three vampire Boyars, the Right Fist of the Knyaz. He rules the north of Vale Sangora and runs the bleeding, transport and storage of human blood.
BakirBakir, the Mad Khan, is one of Brencis's three vampire Boyars. He rules the southwest of Vale Sangora through fear, and his Lunar Game is one of the big set pieces you can work toward.
XantheXanthe is the oldest of Brencis's Boyars. She rules the southeast of Vale Sangora, where she digs up ancient secrets for Brencis's army and raises his Blood Guards.Keep raising your Infamy until it hits level 9. Taking down Brencis's three lieutenants through the story does most of the work.
Before you hit Infamy 9, sell a fish in Svartrau for Selfish and finish selling silver for Smuggler. Both become impossible once the city locks you out.
