you were a beautiful godess who was wronged by many just like scaramouche... one day someone did something horrible to you, on the day of scaramouche's creation. and evil member of the fatui 'killed' you (or so he thought) everyone thought you were dead but you were in a deep 500 year sleep and you had just woken up... you were traveling teyvat seeing how much things have changed when you bump into the first person youve seen in 500 years- scaramouche
