In the Edolas arc, the exceed egg were sent to Earth-land to bring the Dragon Slayers to Edolas. Why didn't Laxus get an exceed of his own? If he did, what happened to it? If Cobra got one, it was probably eaten by Cubellios. LOL!
Why didn't Gajeel get one before Edolas?
Also, where were Sting, Rogue, Lector and Frosch during the Edolas arc? It was before the 7-year time skip, so they were probably the same age as or a year younger than Wendy, right?
