Also referred to as "Asmoday". The Unknown God is the mysterious female god responsible for separating the Traveler from their sibling nearly five hundred years before the Traveler appeared in Mondstadt. The Traveler and their twin faced against the Unknown God, only for both of them to be sealed. She has white hair and golden eyes, and appears to be able to manipulate some sort of dark red cubes that have multiple purposes to them, using them to seal the Traveler and their sibling before.
