Triss Merigold of Maribor was a legendary Temerian sorceress of the 13th century. Called Fourteenth of the Hill by her contemporaries because she was erroneously thought to have been killed during the Battle of Sodden Hill, she passed into history as Merigold the Fearless. A member of King Foltest's royal council along with Fercart and Keira Metz, as well as a founding member of the Lodge of Sorceresses, she was involved in politics for most of her life.

She was friends with Yennefer and the witcher Geralt of Rivia, but also unhappily in love with the latter.[2] Triss took care of Ciri at Kaer Morhen for some time and is like an older sister to her. It was through her intervention that Ciri was not subjected to harmful hormone changes at Kaer Morhen, stripping her of her secondary gender traits.

She was a skilled healer and carried with her many magical potions, but she never used them on herself because ironically, she was allergic to potions, and used amulets to treat herself.[3] She was also quite a powerful mage, certainly when it counted most. She wore an amulet - sapphire overlaid with silver.
