If pure-blooded Garleans can't use magic...

In one of the 1.0 cutscenes, Nael moves so quickly it looks like he's teleporting. I assume Gaius is capable of the same thing since they're about as powerful as each other.

I didn't remember the nael's fight to be such a joke that Gaius's one is though. Poor Gaius, the years made him too old and rusty too fast
