As far as fantasy games are concerned, The Witcher 3: Wild Hunt is one of the most popular - even though it came out in 2015. The base game told about Geralt's fight against the Wild Hunt, but two more DLCs followed it. One focused on Geralt dealing with the demon/devil Gaunter O'Dimm while the second one saw him fighting vampires in the lovely duchy of Toussaint.
Both Hearts of Stone and Blood and Wine introduced a lot of new characters and gave a new meaning to some of the old ones. Not all of them were heroes, some stood on the side of evil, but all of them left their mark on the story. And since they had different characters, their Zodiac signs would also vary.
12 Aries: Anna Henrietta
Anna Henrietta rules Toussaint, and she's a beloved ruler. Arieses are confident, honest, and passionate people who enjoy life and all its possibilities. However, they can also be impatient, moody, and short-tempered. Anna Henrietta has the tendency to switch between moods, one minute she's calm, the next one heads could fly. Luckily, she's kind most of the time and confident in her abilities as a ruler.
11 Taurus: Syanna
The fact that they are persistent and stubborn is the most defining feature of Tauruses. They also don't let too many people get close to them. Syanna takes these traits in a bad direction. She's determined to get revenge on her sister since she believes Anna Henrietta betrayed her. And she'll stop at nothing, even if it leads to the death of innocent people. Syanna can change her mind in the game, but it takes a lot of effort from Geralt's side, and the result is uncertain at best - so many things can go wrong!
10 Gemini: Regis
Even though he's a powerful vampire and can be quite frightening, Regis is a good guy. In fact, he's one of Geralt's closest friends, and their bond dates back to the books. Geminis are gentle and affectionate people. They have the ability to quickly learn things, are adaptable, and curious about the world around them. Regis likes to help Geralt whenever he can and he's not afraid to prove the depth of his friendship. He's knowledgeable and well-read, works as a surgeon in his spare time.
9 Cancer: Damien De La Tour
Damien de la Tour works for the duchess and he remains in close proximity to Anna Henrietta. Possibly because of the important position, he holds as Anna Henrietta's guard, Damien is naturally pessimistic and suspicious of others. He doesn't like Geralt at all when the witcher comes to Toussaint. He later warms up to Geralt, though, and shows other positive character traits typical for Cancers - most notably his tenacity in protecting the city, and his loyalty for the duchess.
8 Leo: Olgierd Von Everec
Leos make good friends, especially at parties. They like to enjoy life to the fullest, are passionate, cheerful, and humorous. They also draw people in thanks to their natural charisma. Olgierd von Everec is like it. He always had people follow him, and they did it willingly.
He made a deal with Gaunter O'Dimm because he was afraid of dying. The deal turned against him, but before it did, Olgierd liked to experience new things and hated being bored.
7 Virgo: Shani
Geralt reunites with his old friend Shani while he's helping fulfill Olgierd von Everec's wishes. Shani is a hard-working medic who's determined to save as many lives as possible. She's kind, helps Geralt when he needs it even though she has a lot of things on her plate. Virgos can sometimes put too much emphasis on work, and Shani has trouble finding the balance between her work life and her personal life - as a result, she's quite lonely.
6 Libra: Guillaume de Launfal
Guillaume is an important supporting character in The Witcher 3 DLC Blood and Wine. He's a knight who courts the beautiful lady Vivienne, and as such, kickstarts one of the longest side quests of the DLC. As a knight, Guillaume has a strong sense of justice, right and wrong, which is a typical trait for Libras. However, he can also give in to self-pity if things don't go his way and it turns out that Vivienne doesn't love him back.
5 Scorpio: Dettlaff
Even though Dettlaff is a presumed villain, he works better as a tragic character. Scorpios are loyal friends who would do anything for the people they love. Dettlaff helps Regis get better when the other vampire almost dies. He's determined to save the woman he loves from captivity but when he discovers that Syanna has lied to him, he lashes out. Violent outbursts are typical for Scorpios since they experience emotions deeply and don't have the best control over them.
4 Sagittarius: Vlodimir Von Everec
Vlodimir von Everec only appears in the game as a ghost - but even when dead, his character traits are obvious. Sagittariuses are generous and idealistic people who have a great sense of humor. Just like his brother, Vlodimir likes to enjoy everything the world has to offer and he loves joking around.
Sagittariuses can come across as undiplomatic since they speak their minds. Vlodimir doesn't mince his words and his brutal honesty sometimes leads to awkward moments, especially once he possesses Geralt's body.
3 Capricorn: Orianna
Capricorns aren't as emotional as other Zodiac signs. They tend to follow logic first, and put their feelings aside. That's typical for The Witcher 3 vampires as well. Orianna is one of the higher vampires, and as such, she stands above humanity and feels superior to humans. Like Capricorns, she can be a bit condescending to others, above all those she believes don't deserve her attention. But she also has good self-control and manages her property (including an orphanage) well.
2 Aquarius: Gaunter O'Dimm
Gaunter O'Dimm is the man who stands behind the miserable life of multiple characters - most notably Olgierd von Everec and his wife Iris. Aquariuses are the most independent and original Zodiac sign. They can be uncompromising, aloof, and run from expressing their emotions. Since he sees himself as standing above humanity, Gaunter O'Dimm fits the description. He likes to toy with people and punish them for their sins, often in creative and inventive ways, but he isn't a human and it's difficult to reach him, understand what makes him tick.
1 Pisces: Iris Von Everec
Pisces have more often than not artistic nature - and there's no greater artist in The Witcher 3 DLC than Iris von Everec. An accomplished painter, Iris lives in the Painted World she created for herself when her husband had abandoned her. She's gentle and sad like Pisces often are. They can end up as victims or martyrs if they're not careful enough. Iris believes her husband and pays for it not only with her life but also the life of her father.
