In order to shine a bit more light on this obvious plagiarism, I have chopped both songs up, taken everything out of context, and reorganized the lyrics to my liking. Riverside lyrics are in red.
"The Fabric Descends"
Part I: Confusion
Please remedy my confusion
I think I'm ready now
But still can't make up my mind
Part II: Failure
That was very foolish of me
I can do nothing now
There is failure inside
This test I can't persist
Part III: The Battle
Nails bleeding from the struggle
It is the end for the weak at heart
I'm bleeding...
I don't mind...
Part IV: Loss
Memories of yesterday
Hopes left behind
A lullaby for the ones who've lost all
Reeling inside
Part V: Regret
Wish I could turn back time
And thrust me back to the day
Oh my Guardian Angel
My gleaming eye in your necklace reflects
Stare of primal regrets
Part VI: Departure
Take me away from here
You turn your back and you walk away
I have to fade away now
Like Autumn leaves left in the wake to fade away
There's no other way out
On a side note, please note that I am being facetious, and I am not accusing anybody of anything.
