Now then, it's time for a theory—an Arukana Theory. *plays shitty music* Now, I believe that the Dragon Lacrima that are implanted within God Serena will be used for two different purposes in the future.

The first purpose is to implant the Lacrimas that are the same or similar element as the current First Generation Dragon Slayers. Obviously, Natsu will inherit the Purgatory Dragon Lacrima which I theorize is 's unique brand of Dragon Slayer Magic and Wendy will inherit the Hurricane Dragon Lacrima or, just for the sake of a nod to what she was originally meant to be, she could also get Neptune Dragon Lacrima as Wendy was meant to be a Water Dragon Slayer originally.

The second purpose is to fool Acnologia. What I mean is that Acnologia is currently looking for Dragon Slayers. This means that by implanting the remaining Dragon Lacrima into other mages, they can use it to momentarily distract the Black Dragon King of Gajeelness. I feel like the if Wendy doesn't get the Neptune Dragon Lacrima, Juvia will acquire that which I really hope doesn't happen and Jura will acquire the Cavern Dragon Lacrima since they have a vast amount of experience in using said elements.
