Help me explain a prophecy

In the Iadate, soothsaying and future-seeing is an art practiced in every court. This is done by the Wenna Mystics, a group of people that have bonded their souls to a Caercandarum spirit in an incredibly dangerous and painful ritual. These visions are usually flashes, uncertainties and gut feelings more than the typical High Fantasy prophecies, except for one.

On the 3rd day of the Harvest Cycle, 333, all Mystics across the continent experienced the same exact vision, which was painful in how clear the images were. One of these, the Isdri Poet-Mystic Caor Nanaar, translated the visions into a prophecy, which was then spread across the continent:

Ten and ten and ten again

Shall be their final number

When blood is all and blood is lost

And land is churned asunder

When battered shield meets shattered spear

Are ancient rites awoken

Then screams arise from fields of grey

And golden shackles broken

Ten and ten and ten again

For when they're counted all

The strongest rock will crush to dust

And the highest tree shall fall

For when lamps will shine with darkness

On that day the wordless sing

Shall knots unfurl and patterns fold

And in them, chaos bring

My question to you is, I don't know what this prophecy foretells or what each line (or word) could be interpreted as. So in the spirit of prophecies and ambiguity, let's hear your interpretation. The best ideas will become canon for my future worldbuilding.

Good luck
