Find the Center
The quest for the heart is so commonly undertaken that it has entered common parlance as a metaphor for any journey where you seek something of value. But true delvers know that the quest for the heart is neither easy nor common.
As mazes go, the challenge is not extreme, there being several navigable paths to the center. However, the barriers on the way are so pernicious, that more than one confident seeker has been sent packing. You've probably met some; disillusioned adventurers who loudly claim there is not heart after all, its a chase after smoke, an illusion, a ruse.
But the heart is there still and, if the tales are to believed, well worth the finding. Happy valentine's day!
