Well, while working on Jakuri’s Lv. 6 scripts, I found this little line (it’s the answer to a question that Croix makes during a certain point):
???(132) :2:2: JP::シルヴァホルン。<LINE> 世界の詩魔法力の源にして、世界を支配する力を持つもの。 EN::It’s the Silver Horn that can rule the entire world by using all the magic power it can absorb. NEW:The Silver Horn. It's the source of Symphonic Power for the world, and as such, it also holds the power to control the world itself.
To me this doesn’t seem to convey the same meaning at all (especially after knowing what was the Horn’s purpose in the story of the first Ar tonelico and how it’s related to Jakuri). And on another note, I have noticed that the term “Symphonic Power”, which was so important and used extensively in Ar tonelico 1’s localization (as the equivalent for “Song Magic Power” or “magical power”) is completely absent from the localization for Ar tonelico II.
