Ciri

Ciri joined the system in late 2018 and became a primary fronter in 2019. She has memories from three separate timelines, as well as several kin canons.

Witcher 3 Compliant
The events of this timeline largely mirror the events of Witcher 3. After sealing away the White Frost, Ciri went on the path briefly before settling in Toussaint with Avallac'h where they raised their children, Duny and Lara.

In this timeline, one of the worlds Ciri and Avallac'h travelled to while under pursuit of the Wild Hunt was Thedas, which was a world colonized by the Aen Elle prior to the Conjunction of the Spheres which brought humans and dwarves to the world.

Nilfgaardian Empress
In this canon, Ciri was captured by Nilfgaard after being teleported away from Thanedd. Upon arrival to the capital she married Emhyr var Emreis and became Empress, as well as reclaimed her previous royal titles. In this timeline she was unaware of her relation to Emhyr.

She had three children, two with Emhyr and one with her lover Morvran Voorhis.

Queen of the Aen Elle
Ciri remembers little of this timeline currently. The primary characteristic was her marriage to Eredin Bréacc Glas after the Wild Hunt overpowered her allies at Kaer Mohren after paralleling the events of Witcher 3.

It is likely that in this timeline the Aen Elle successfully laid claim to Ciri's home world.
