Why can't Earthland magicians use magic in Edolas without the X-balls?


When Natsu, Wendy, Happy, and Carla went to Edolas, they couldn't use magic at
first. Later, Natsu and Wendy were given the X-balls to regain their magic
usage. Yet, even without the X-balls, Exceeds could use their magic. This is
according to [the wiki](https://fairytail.fandom.com/wiki/Exceed) because they
have their Magic located inside of their bodies **just like the Mages of Earth
Land**.

If both have their magic located within their bodies, then why are only the
Exceeds able to use their magic, but Mages need those X-Balls?

Also related to this question, I was wondering why the Exceeds even lost their
magic usage, to begin with. It was said that they need to have the right
mindset to be able to use their magic, but when they entered Edolas for the
first time, they didn't know magic was limited, so they were supposed to have
the "right mindset" at that time right? So why did they lose their magic usage
when they arrived?




To answer your first question: because it's said so. (Possible explanation
could be that Exceeds were laid there, so their bodies has some mechanism that
they just needed to awaken but mages needed the X-balls for that. But this is
just a speculation as we only know as much as it's said: mages needed the
X-balls, Exceeds didn't.)

To answer your second question: they were not supposed to have the right
mindset. They were pretty much in doubt about everything, especially about
themselves. What are they, what are they for... what they knew so far changed
quite drastically in a few hours of time. While it's not stated explicitly in
Fairy Tail, in most of the other universes (including RPGs), using magic needs
quite some concentration, so that "right mindset" thing can be more crucial
than you think.
