Thingfish's Riddle

[Lenna]

Confused, the vulgar see vengeful death's course,
Heaven's flute scourged, even focus slaughtered.
Yet displace determiner from this source,
A riotous assembly remembered.

"This source" is here the first two lines. They make out a rioutous assembly of letters which must be re-membered(ie. rearranged) before we can remove the determiner "the".

Basically, the two first lines of this verse contain a very complex puzzle concerning the letters of the lines. Once you have correctly rearranged them, you must remove the word "the". By succesfully doing this, the puzzle will give us the full name of the answer.

If I remember correctly, Thingfish didn't say that the answer to the riddle was in that puzzle. I believe he merely said that after solving that part of the riddle we'd be in stage 2 where he'd give us a better detail into what we need to do next. I don't think he said that rearranging those letters would actually give us the answer's name.

Regardless of if he said that the answer is in the fourth verse or not.

Yep if you read my post before, you shall see that all the hints/clues I posted were quotes said specifically by Thingfish. Amongst them was this:

Confused, the vulgar see vengeful death's course,
Heaven's flute scourged, even focus slaughtered.

Look at the two lines more closely, and after you've worked how the puzzle within them, which is unfortunately very, very difficult, only then remove the 'the'.
the puzzle has to do with the actual letters.
(We have to arrange the letters)

working out the first stage of the puzzle of those two lines won't tell you anything about the name of the answer. That's the hard part about the second stage
