Narnia (ナルニア, Narunia) is a fanfiction anime by LDEJRuff, based on the Chronicles of Narnia book series by C.S. Lewis. It features a group of children going on adventures to and from the fictional land of Narnia, where animals talk, magic is real, good fights against evil, and a lion rules over all.
Each season in the series is referred to as a book, and is based on a specific book in the series. There are five seasons in all, and two OVAs (one that takes place before the series, and one that takes place during the near end of season one).
