Also known as: 丝柯克, Skirk, 虚渊暗星, スカーク, スカーク(原神), 原神丝柯克, 스커크
A playable character from Genshin Impact who made her first debut in Version 4.2. She is the disciple of Surtalogi (Genshin Impact) and was also Tartaglia (Genshin Impact)'s master during his time in the Abyss, training him to use the Foul Legacy Transformation.
Her arms and legs are prosthetic limbs made of purple crystalline Abyssal energy, as her original limbs were irreparably damaged in her childhood. In fanart, they may be drawn as Colored Extremities or as clothing like Elbow Gloves and Thighhighs. She also has a single, small dorsal fin on the left part of her back.
