Triss has a long history with Geralt, although after he is stricken with amnesia in the first game, he does not remember much of it. She loves Geralt, however her political influence and responsibilities often keep her away from him for quite some time. Triss is a member of the Lodge of Sorceresses, a powerful advisory organ serving the king of Temeria. Although she is capable of performing amazing feats of magic, she is also allergic to it, and needs to recover from wounds normally or by the use of potions, rather than with healing spells.
In the first Witcher game, Triss helps Geralt, offering him guidance during his quests and healing him after a near-death experience. When Geralt discovers Alvin - a child who may be an unstable magical being known as a 'Source' - Triss insists that she be allowed to oversee and protect him from those who would abuse his powers. Geralt may choose to leave Alvin with either Triss or Shani, another character (and the other full romantic interest for Geralt) in the game.
The Witcher 2: Assassin of Kings
Triss and Geralt are together at the start of the game, aiding King Foltest in the the assault on the La Valatte's castle. After Geralt is freed from his imprisonment, Triss joins him as he sets out with Roche in search of Foltest's killer. It is not long before they discover the assassin, but before he can be captured, he kidnaps Triss and forces her to magically teleport the both of them away, meaning Geralt must now rescue her.
The Witcher 3: Wild Hunt
In the third game, Geralt and Triss reunite in the free city of Novigrad, a long while after the events of the second game. To hide from the witch hunters, Triss had to go underground where she leads a group of mages in a quest to escape the city.
- Triss is voiced by Jules de Jongh in the first, and by Jaimi Barbakoff in the second and third game.
- During the promotional run-up prior to the release of the Witcher 2, the May 2011 issue of the Polish edition of Playboy Magazine featured Triss Merigold as its cover girl - a marketing stunt that called back to the 'sex cards' of the first game.
