*Lin: It looks like you've finally reached the Great Tree of Life!
 	
*Lin: The monsters you just faced were probably the protectors of the Tree!
*Lin: I'm relieved they weren't too strong though.
*Lin: Well, the empress's treasure should be around here somewhere...
*Lin: ...but it doesn't look like its location is that obvious.
*Lin: Maybe we should look around a bit more...
 	
*...........................
 	
*Lin: Well, there really doesn't seem to be any place around here that could be hiding a treasure chest inside.
*Lin: Hmm... Maybe that rumor about the treasure was just a rumor after all?
*Lin: I mean, rumors are called rumors because their validity is questioned, but that's unfortunate...

*Traveler who has reached the Great Tree of Life. Seek for the treasure that reflects in your eyes.
*However, one piece will not suffice.
* Three must become one to guide the way.
*Once all of them have been gathered, the door of memories past shall open.

*Lin: Hmm, are these some kind of instructions?
*Lin: According to what it said...
*Lin: ...we have to find these 3 "pieces" and bring them all here...
*Lin: ...and then something will happen, maybe?
 	
*Lin: That's not enough information to go on at all!
 	
*Lin: Anyway, you made it to your destination, so we can consider your mission complete for now!
*Lin: Lugina is not here yet, but running into him might not turn out for the best...
*Lin: ...so please get back as fast as possible!
 	
*Lin: But, now I'm very intrigued by all of this...
 	
*Lin: Oh, my apologies! Please don't mind me!
 	
*Lin: Well then, until next time, ! Job well done!
