From his first marriage to Beatrix of Kovir he had a daughter, Falka . Later he remarried to the beautiful Cerro. Apparently their courtship is the stuff of legends. He and his wife also adopted the orphaned Riannon, Lara Dorren's daughter into the royal family. During the short story "A Question of Price", queen Calanthe sounds Geralt out about his convictions about his profession.
He was killed along with his wife Cerro and sons Heltmult and Denhard  during Falka's rebellion, in which Falka tried to take the throne. Falka was convinced that the throne belonged to her, and not to the children from her father's second marriage. During the rebellion Riannon gave birth to twins: Fiona and Amavet. Meanwhile, Falka bore Vridank's granddaughter - Adela; the three children later became known as the Houtborg triplets.
After the defeat of the uprising, the throne was taken over by his uncle - Vizimir I the Old.
Zoltan mentions Vridank (and his bride) over the course of a rather philosophical conversation with Geralt:
|Nicely put, but as young Cerro said to King Vridank on their first date: "Does it have any practical uses?"|
In The Witcher 2, in Flotsam, you can hear the conversation between merchant and guard. Curious mercenary looks into crates and barrels asking what is there. While the buyer is responsible to him with exasperation: " The Treasures of King Vridank". The guard looks to the next and repeats the question. Next the answer is "Amber Room", which is a reference to the famous treasure that was lost during World War II.
From the in game book : The Chronicles of Redania Edit
- Vridank the Elf
- Despite what one might conclude from his moniker, not one drop of elven blood flowed in King Vridank's veins. They called him the Elf because of his exceptional beauty, and for the great admiration he felt for the Aen Seidhe. This fascination, seemingly harmless, would have horrible long-term consequences. King Vridank, spitting in the face of all laws and customs, chose as his wife a half-elf – and one of low status at that – known as Beatrix of Kovir. The fruit of this regrettable and short-lived mésalliation was Falka, who later fomented bloody revolt against her own father. Though this uprising was ultimately extinguished and Falka herself burned at the stake, the young state was thereafter thrown into chaos for years to come.
