I had the amazing pleasure of beta'ing
planejane's
A Thousand Whispers, which
alby_mangroves illustrated.
YOU MUST GO READ IT. It's about 25K long and just gorgeous. It's a Mordred story with the endgame being Merlin/Mordred/Arthur. PJ is brilliant. Alby is brilliant. It's a match made in heaven. Just go. NC17. You can thank me later:)
Also, it fills that KMM prompt that someone wanted based on a picture and Mordred is in the middle:D
