The Criosphinx's Riddles

[Boo the Gentleman Caller]

In the beginning there was only
Large and in charge,
Never changing, ever ending
You make me blue in the face

It was a nu!

All BEGINS and ends nu,
Large and robust looking
Never changes and is in every era
And they're blue

Good job!

[Kodokami]

I am four, and six, yet seven
But always one
Depose the serpent of Eden
And thy deed is done

[Boo the Gentleman Caller]

Is it magic? The first and second lines make me think of the series' magic.

Chrono Trigger has four elements, Chrono Cross has six, and the actual Chrono Cross element itself is seventh element.

However, I can't figure out the serpent of Eden. I assume this is a reference to Satan (as in from the Bible?), who was a snake in the Garden of Eden.

Wait... Is the answer is actually the Chrono Cross element? Since it's all of the above and the only thing capable of destroying the Time Devourer, which is the big bad and sort of the equivalent to Satan (aka enemy numero uno).

You're right on about the magic, though I was actually thinking of something, or someone, else. The "serpent of Eden" is both a reference to another character and also a physical location in the series. Good guess!
