Babelfish tells me the title means "east magic"... but would that refer to Schierke or the Kushans? (most likely Kushans, of course, since Schierke's magic is nothing new by now) I thought that Vritannis was on the western coast, but I guess I was mistaken. It would make more sense for the Kushan empire to be in the east anyway (and yes, I realize the Berserk world is probably round, too...)
