The last time Xander had played the Archeon's Flute, it was in the real world, and he had Master Arwin guiding him the whole way. However, this time, the situation was completely different.
He was now inside a Dreamscape, and he wasn't trying to mollify aggravated Ethereals. Instead, his task was to play a tune that would lure the Gloacas back to the pen.
To an untrained initiate, it would have sounded easy enough, but Xander knew the flute had to be played in a certain manner to lure Ethereals without provoking them. If the melody wasn't correct, it could turn even the friendliest Ethereals hostile and create havoc.
The other problem that could arise by using the Legendary Relic inside this dream was that it did not differentiate between various types of Ethereals. The flute's melody would attract every Ethereal that could hear the tune.
