Hay,
This is a Guild Wars 2 Cosplay from Yennefer van Vengerberg out The Witcher.
Yennefer, born on Belleteyn in 1173, was a sorceress who lived in Vengerberg, the capital city of Aedirn. She was Geralt of Rivia's true love and a mother figure to Ciri, whom she viewed like a daughter to the point that she did everything she could to rescue the girl and keep her from harm.
