Solution to Cthulhu

Each of the Cthulhu puzzles contains some flavortext with some corresponding code symbols. Words are encoded by converting each syllable's letters to one symbol, with spaces and punctuation preserved. Each letter within each syllable encodes a type of transformation, applied in succession to the following base symbol:

This puzzle shows the encoded titles of all of the constituent puzzles' titles, along with the encoded versions of their answers, but the answers have one extra letter's transformation added in. The encoded answers are not revealed to solvers until they've solved the given puzzles. The extra letters inserted into the encoded puzzle answers spell out, in order, FEED ME YOUR SOLES, the answer to this puzzle.

The list of transformations is as follows:

Letter Transform Example A Add ⟍ at (−2, 0) B Add ⟋ at (0, 1) C Add ⟍ at (0, −1) D Reflect about x-axis E Add • at (2, 0) F Add • at (0, 1) G Add ⟋ at (2, 0) H Connect (0, 1) with (2, 0) I Add ⟍ at (0, 0) J Reflect about y = −x K Add ⟍ at (0, 1) L Rotate 45° clockwise M Add ⟋ at (−2, 0)

Letter Transform Example N Add ⟋ at (0, −1) O Rotate 30° counterclockwise P Connect (0, −1) with (−2, 0) Q Switch the shapes at (−2, 0) and (0, 1) R Add • at (0, −1) S Add ⟍ at (2, 0) T Add • at (−2, 0) U Reflect about x = y V Connect (0, −1) with (2, 0) W Add ⟋ at (0, 0) X Switch the shapes at (0, 1) and (2, 0) Y Reflect about y-axis Z Connect (−2, 0) with (0, 1)
