The pipes in this puzzle follow the rules for the pipes in the original Pipe Dream crossword from the 2006 Mystery Hunt (except that there's no restriction on which pipes can carry consonants and which carry vowels, and there are warp zones). Red pipes use the warp zones; each red-pipe word includes the letters from both the warp zone it enters and the warp zone it exits. These letters are underlined on the list of clue answers below:
The red pipes impose a cyclic order on the warp zones: if warp zone i is the one that a given red pipe enters, warp zone i+1 is the one that that red pipe exits. In this order, the letters in the warp zone squares spell the answer to the puzzle, BARRY ALLEN.
