Forgotten Vision (Genshin Impact Fanfiction)

A girl with a bit of a complicated life was gifted a dendro vision when her friend was hurt. Her desire to defend and heal her friend ignited a desire that burnt so brightly even the archons couldn't look away. Because of this, she was given her vision, just in time to save her friend. However, what happens to a person once their vision is broken?

Do they lose their ability to use the element they were gifted with or do they retain their ability? If it's the latter, what happens to people who use their element without a medium? Without a vision? Will it kill them? Will they be fine? Or perhaps they really will lose their ability after all.

However, this isn't the case for the Hailey. Using her element without a vision. It's unheard of. She didn't lose her ability, is it because of her desire? Or is it something else? Something bigger perhaps?
