theonewoody asked: How about Caster!Elsa facing off against Saber for the Holy Grail. We know why Saber wants it, but Elsa needs it to bring Anna back because she died in after the movie ends. Another prompt could be a modern AU with Anna saving Elsa from an assault/mugging heroically. She turns to see who she just helped to make sure she's okay and "oh no she's perfection send help"

Oh, boy…your first prompt feels like it really can’t be confined to just 3 sentences. But I tried. Sorry this is late, too.

Prompt 1

Elsa was not a fighter by nature, but with Anna’s fate on the line, she would gladly take on anyone who stood in her way…even the legendary King Arthur Pendragon.

Saber dodged the ice spikes shooting up from the ground–invisible Excalibur cutting through whatever she couldn’t avoid–as Elsa waved her hands; a conductor orchestrating the knight’s funeral dirge with blinding snow and deadly ice as her melody.

Her power flowed through her fingers, weaving its deadly beauty through the air…and if she listened carefully…Elsa could almost imagine Anna’s breathless “Do the magic!” in her ears…

Prompt 2

Anna tried not to make it a habit of getting into fights, but a mugging occurring less than ten feet away was just something she couldn’t ignore. The thug seemed better than average as far as muggers go, and she found herself having to use some of her more complicated maneuvers before she was finally able to knock him out.

And Anna might as well have been knocked out herself with how utterly gorgeous the woman she had rescued was.

Epilogue: Elsa takes her out to eat as a thank you. Everything spirals from there.

To Anna’s delight.
