you are to me an excellent poet so I feel comfortable with making suggestions as I would in a poetry workshop.
I would drop the entire first part. The first stanzas show us your love of words, image, sounds and romanticism. They are important tools of the craft, but in this poem they do not engage me with substance. Then the telling of the two sides of stories and coins is too telling. Here is how I would suggest the poem might be considered:

In between the burning rays of the sun
and the ice cold stares of the moon
lay the vast plains of unexplored grey.

Terror awaits to intervene into slumbered dreams
with eyes burning red they kindle the nightmare fires,
talons open the clench in fitful anticipation.

Phantoms awaken with banshee cries
to the alarm of rattling bones
and join the other stalkers of the night

As daylight breaks on the distant crag-
the sun, now bloodstained, is rising!
once again the land is at rest
until dusk reveals it's surprises.

To me this opening is very compelling and poetic. The opening stanza draws us right into the mystery of the poem. It is really greatly done.
In the second stanza I removed "someones" as a distraction and "peaceful" since slumbered suggests the peacefulness and the whole increases the line to the form in the poem.
In the last stanza i removed "yonder" as it feels archaic and reaching for too much poesie and suggested distant. I changed the syntax to allow the stanza to be joined with the previous rather than start as an independent sentence.
I put some punctuation in to see if it might help. They help me often as a tool we have in poetry to add a different coherence in a poem.
I think your poem has good power, a strong vision, and I hope my suggestions are helpful!

There is an abstract metaphysical metaphor you have in your head in the opening which i'm just not catching the core of. .. the first stanza we are in spring, in the fourth stanza we are introduced to ice crystals.... the two sides of everything ,,
from a personal point of view I do keep my poems and ideas well organized, and sometimes I very much get trapped in a paradox and just have problem getting the idea translated into a poem..sometimes, or mostly, I use some of the good and sharp images, (which you have several of in the first part,) in another poem... I know they are out there ready to be used. I would sit on it a while. But I love the second part as I presented it.
But just my take, as always, with honesty and respect.
..

I enjoyed the read and could sense the transition of landscape and mood ...great use of literary devices which makes it possible...

just a small query...did you mean "this" instead of "his" in line 6?
