I have one clue left.
A clue has either a misprint in def or an extra word to be removed.
32. Eatery belonging to thee on the main (4) TH?N
I think this is about the Greek stories of transformations. My knowledge is zero.
I see a wind god in SE corner.
I need some hint on how to find the four characters.
Think of the possessive form of 'thee', but only 'in the main' - this will give you a synonym for the first word, where there is a misprint.
Have a scout around the 'a' from 22d - that will lead you to a god, who in turn with the source in the shaded cells, should lead you to the right story, with the rest following.
