Lost Fic Rhaegar Wins AU

I'm looking for a AO3 fanfiction that I remember reading maybe 5 years ago? It was a Rhaegar Wins AU but I think Rhaegar was very injured. The relationships I remember are Jon/Arya, Robb/Daenerys, Jon/Daenerys (past/secondary). The title might have been Fisher King or The Fisher King but I'm not sure. No combination of tags brought up anything like this so I think the fic was taken off AO3.
