[ In the modern era, Zeref learned the hard way that he didn't know everything about magic anymore. Ultear's Arc of Time magic was something he didn't see coming, regardless whether or not his own Death Magic was weakened by his unwillingness to kill her. But here? In an entirely different world? Zeref might have been able to get the Eclipse Gate working, but inter-dimensional travel is a whole different kettle of fish. Especially when those other worlds clearly have magic so different that they don't even work the same way as they do in his world. ]
I'll have to find out more about magic from other worlds.
