Crossbishop and Venator(2006, Winther), having bifurcation modes, are new
pieces in the argument. (Venator's two legs mandatory, Crossbishop's 'if
and only if' capturing)

If Pawn-d1 moves or Pawn-f1, one of Elbow Rooks has path.
If Marshall-c3 moves, Venator has path a8-a7-a5-b4-c3-d2-e1.
If Knight-c4 or Pawn-d4 moves, Dragon has one or two pathways.
If either Cardinal-e3 or -e4 moves, Cannon has path(illegal).
If Bishop-f4 moves, Wolf has pathway g6-f5-f4-f3-f2-e1.
If Rook-g3 moves, Crossbishop has pathway i8-i7-i5-h4-g3-f2-e1.
If Pawn-g4 moves(captures), Fox has pathway g5-g4-f3-e2-e1.
If Queen-g2 moves, Quintessence has pathway.
King cannot move because of Elbow Rook-b6. (14)
