Genshin Impact's Skirk was first mentioned by Childe, 11th Fatui Harbinger, as his former trainer and a woman he met when he fell into the Abyss. However, very little was known about Skirk to him or anyone else, as he was never able to find her again. Despite being one of Genshin Impact's deadliest Harbingers with a vast networking system at his fingertips, Childe found no traces of her for years.
