What is it that lurks in the center, that is the source of this code?

The third line is like the autokey, but different.
A nested cipher, the keys are found within.

Hint 2:

Let the trail guide you, let each key guide you to the next.

  • $\begingroup$ @NL628, If it helps, the first word of the third line is each, and the puzzle relies on decoding the remaining parts with different keys. $\endgroup$ Commented Mar 22, 2018 at 11:31

Partial Solution

From the first line, we get

A trip to Rome shall do. I found this by plugging it into a decoder on quipquip.com

The first line was, in fact, about

Rome, so plugging the second line into a Caesar Cipher, we get "What is the Key?"

I've tried

"What" and "Caesar" and "Rome" for the third line, but none of these keys work.

Partial Answer:

When run through an Atbash cipher, the first line reads "A trip into Rome shall do."
This gave me the idea to use a Caesar cipher, so using a rot13 on new code, the second line now reads "What is the Key"
This is where I got stuck. I've tried using "what" as the key to a Vigenère Cipher, but to no avail.

    $\begingroup$ If you run the last line through all the ciphers you mentioned, the first word becomes "each". It may be a coincidence, but then again, it may not. I checked the Autoclave (autokey Vigenère) cipher too, since it works identically with Vigenère for the first word, but sadly, to no avail. I also tried to guess the keys so that the single letter words would both turn into I or A, but no success there either. $\endgroup$

    $\begingroup$ tried using portunus as the key as well (roman god of keys...) $\endgroup$

Partial answer,

First Line,

When I put this into a backwards decoder I got that the first line says "A trip into Rome shall do."

Second Line,

Is "What is the key" from Matthew King

Third Line,
