This is set after Sora leaves. Sinbad tells Aladdin, Alibaba, and Morg how he met her when he was a teenager. It was after he set all of the children that were slaves to Aum Madaura. As for Sora as a kid, it is set before Igneel disappears. He brings her to Magi world to train and get stronger while Natsu as a kid stays in Fairy Tail world and trains with a copy of Igneel. I don't own Fairy Tail or Magi, only Sora.
