Breathtaking, simply breathtaking...
Whole piece is excellent, it brought me to another world and wrapped me in the vivid imagery that you created. Original from the first to the last line, with superb descriptions. I like your choice of words a lot, they paint pictures that suit my imagination.
My favorite lines are:

-She was his gem with jagged edges and the phantasmal persona
who would destroy his apathy and leave him to mourn.
She was the daughter of the moon and heiress of time
with a voice that would feast upon stars.-

The ending line is also very effective, it rounds up the whole poem greatly.
I love the mythological and fantasy content that you added, it gives to the whole piece flare of beauty and uniqueness.
Keep writing!

You are a very gifted writer! :) loved this one too :)
