Lets save each other some time here. Post anything you've tried that turned out to be totally useless.

Lol - HERE'S an hour I'll never get back - I took the first letters of all the words in the first clue, (100 letters.......) and made a full ceasar shift grid. Nothing. Then tried reading diagonals on the grid.... still nothing. Don't waste yer time.....

Tried to vigenere the sequence of 100 letters with these keys: egg, easter, easteregg, scroll, scrollquest, common, swim, key, (and a few others I cannot remember.)

I doubt taking the first letters is the key to this one.
