(Clarification: the "p" to the left of the "L" is lower-case. The "P" below the "s" is upper-case.)

Hint 1: When drawing the path, indicate direction of travel on each segment to help solve this.

While the rules as written will allow you to backtrack - pick up a parchment and leave by the same path you entered on - this then allows multiple solutions, some of which are not the "right" one. Hint 2: Some paths can be drawn in immediately; e.g. between the U and k and s, since there is only one path into and out of the k. Note that you can also tell the direction of travel due to the lower-case to lower-case rule. Hint 3: The upper left corner has to be R-->v-->o because of the v having only one entrance and exit.. Hint 4: The lower right corner has to be M-->z-->h-->G-->b-->Z because of the h having only one entrance and exit.. Hint 5: The end of the maze has to be D-->E-->N-->d The Solution: The final solution is:

T-->r-->A-->t-->S-->a-->M-->z-->h-->G-->b-->Z-->x-->p-->L-->i-->P-->s-->k-->U-->n-->l-->f-->c-->I--->y-->B-->W-->Y-->g-->e-->C-->R-->v-->o-->F-->J-->K-->Q-->V-->X-->j-->H-->O-->w-->u-->q-->m-->D-->E->N-->d
