Story
Queen Remedi died from an illness, but she somehow lives on in Ivalice. However, she's not what she seems to be. Remedi does everything she can to keep the fantasy world of Ivalice in existence, constantly thwarting Marche Radiuju's attempts to revert it to normal.

When her husband, Judgemaster Cid, leaves after learning Ivalice isn't a "real" world, Remedi creates a evil clone of her son Mewt, and calls him Llednar Twem, she then sends him to destroy Marche. Llednar is eventually defeated, and Queen Remedi is destroyed in the process.
