"who am I?"

18=1, 20, 21

I am truth
before the heavens I was taken.
It was very dark but I flew.
The era of the mistaken.
It seemed like a very few.

There were many.
The crystal was shiny.
It was all silly.
Unwisely bloody.

Very necessary
but undetectably steady.
As it was supposed to be
but indirectly.

It will be a dark secret
but undeniably
obscure and detectably
undisguisedably .

We all know
it is disposable and
misguidedly
undirect

Unstoppably fine.
Directly guided.
Uncontrollable.
Philanthropically viewed.

I'm not you.
Controllably doubted.
Uncontrolably misguided
You had to fit in a tube.
