I don't dislike the other two tracks but What Lies Beyond is easily my favourite, really has that "the truth unveiled" sound to it, very effectively got across through the melodies & instrumentation, love that.
Only thing I would say is that maybe the bell and choir sounds should be a touch less dominant/overpowering? Both work really well still though.
Love that arpeggio and flute(?) melody in the calm section. And absolutely love the strings and woodwind in the more ominous sections. Kinda feels like mid point between several tracks from FF7 & 9 but with unique identity of its own.
