An excellent #MLP and #HarryPotter#fanfiction#crossover: Harry Potter and the Lunar Princess, by psistarpsi: "Princess Luna encounters a dream like no other after Harry Potter’s third year at Hogwarts and Harry Potter’s life is forever altered. Rated M for battle sequences, violence, and implied adult themes. Harry Potter plus Cartoon force = BAMF Harry." archiveofourown.org/works/66130705/chapters/170429845#fanfic#mylittlepony#xover#fimfic#fimfiction
