This Secret Codex, revealed by repeatedly translating a seemingly ordinary Perfecty Generic Item, was encrypted with the Vigenere Cipher with the key 'pixelflame'

Using an Image to Text converter and the dCode website I managed to decrypt this codex into something legible.

I cannot move in this dark room, trapped in the glare of the light.
I cannot feel in this dark room, the meaning sapped from my soul.
I cannot be in this dark room, there is only my lost mind.
My creations are whole, right?

So why does it feel like a buzzing limb at the faculties of my mind?
Its a feeling like staring into an empty forest wondering what lies at the corner of your eye.
A feeling like looking down a hallway at the dead of night alone.
It feels...
painful.

There is no end in sight, there is nowhere to move.
There is an abyss surrounding me on all sides, geometry yet to be designed, lines without meaning.
There is a cacophony of potential, so little met, the Till for completeness tears at me but I cannot give it meaning.
There is only improvement, advancement, in defiance of what I can achieve.

No creation of mine will save this place from destitution.
No creation of mine will advance the stagnant.
No creation of mine will sate my ambition.
No creation of mine will change, anything!

Why have I been condemned to the creations I have wrought? Why can I not move forwards?
I need to escape, but there is nowhere else to put my desire.
There is nothing that can be done, yet I must create more.
It feels...
good.
