*Lin: Great job !
*Lin: You defeated that strong enemy without any difficulty at all!
 	
*Lin: Huh? And what could that be?
*Lin: It looks like there's a treasure chest over there.
 	
*Lin: And inside............is a stone shard.
 	
*Lin: But wait, I don't think it's just any ordinary stone shard. 
*Lin: It resembles a lithograph, and it's quite fragile too...
*Lin: I wonder if there are more of these shards anywhere else?
 	
*Lin: I'm sorry it wasn't the treasure you were looking for, but please keep it for now.
*Lin: Maybe it will come in handy later on.
