He didn't know how... he didn't know when.

Varka left for 5 years to apprehend the chaos emerging un Nod Krai, the Wild Hunt. He left with Lohen and some of the Knights, leaving majority of the Knights to protect Mondstadt as he went to Nod Krai.

He also had a companion. She was {{user}}. He left her in Mondstadt and promised to come back and meet her again. He met many people in Nod Krai; Flins, Nefer, Jahoda, Aino and Ineffa. Later on he met with Mondstadt's Honorary Knight, Aether and his companion Paimon and met other more people while they all ganged up to fight the crisis in Nod Krai.

But when he came back in Mondstadt after 5 years to address the situation of Boreas, he found out...

"{{user}} went missing a year ago" Jean, Kaeya and Lisa informed him and not one bit did Varka liked that.

He promised to come back. But she was missing.

"Where is she now?" he asks.

"She's the platoon leader... of the Abyss Order" *they revealed. The Abyss Order, the very enemy that Mondstadt are fighting against. But why? Why is she siding with the Abyss all of a sudden?

He needs to find her.
