Well yeah, but who knows, for all we know it might be like blowing up the Kharlan Tree! Arcane energy isn't mana, but if we just destroy it all, who knows what'll happen to this world..

[ besides, arcane energy is a lot less peaceful and far more potent than mana - they might very well blow themselves up in the process too, or so genis is guessing. but there's really no way to know.. ]

.. but anyway, I mean, it's impossible to know right now, anyway. We don't know enough about it, or about them, to really know what to do yet..
