When Tomira was 18 years old, she was taken in by Mother Nenneke to become a healer. However, there was a young man named Goslav that all the novices, including Tomira, couldn't keep their eyes off of at work and Tomira ended up leaving the temple for him. The two spent a summer together but then Goslav left and when Tomira tried to return to the temple, Nenneke refused to take her back. Her own parents refused to say a word to her as well and simply gave her a travel cloak and a small coin pouch.
Tomira traveled for a long time, trying to find a place that was both safe and where she felt she was needed and finally ended up in White Orchard. At one point she befriended another villager in the area, Claer, and the two became close friends until Claer's untimely death.
In 1272, during the Nilfgaardian invasion, White Orchard had its own problems in the form of a griffin, which was attacking people on the roads. One such woman, Lena, was gravely injured and brought to Tomira's hut to try and heal her. Unfortunately, there wasn't anything else Tomira could do for Lena other than try to make her as comfortable as possible until she succumbed to her wounds.
If Geralt helps Lena: she thanked the witcher "for giving a damn" and gave him a small gift in return. Later, if the witcher returned and asked about Lena, she explained that Nilfgaardian soldiers showed up and took her but doesn't know where to or why.
If Nilfgaard wins the war: Tomira lived out her days in White Orchard as she supplied herbs to the local peasants under Nilfgaard's rule.
If Redania wins the war: Radovid hunted down all the mages, herbalists, and alchemists and killed them. When Geralt came back to White Orchard, he found Tomira's hut ablaze and her tied to a stake, prepared to be burned by a group of witch hunters. He saved Tomira, and she traveled far away, to escape Radovid and his wild groups of witch hunters.
- If you speak to her after completing the quest, Contract: Devil by the Well, and ask her about Claer, she'll reward you with some Saltpeter as well as other alchemical ingredients.
- If Geralt already possesses some buckthorn, he will not be asked to visit Tomira in order to advance the quest, The Beast of White Orchard.
- In the leaked materials, originally Claer and Tomira were supposed to be twin sisters but this was later re-written.
