With Chains Bound in Rust

This is open to interpretation; but I write this about being brought out of a very dark depression.

Once upon a time,
In a land of malice and dust,
The earth bore a young girl,
With chains bound in rust.

Deep in a cave,
They kept her hidden;
For her to even once glance upon the light
Was exclusively, to her, forbidden.

Minutes were hours,
Hours were days,
Her eyes were never bid to drink in,
The lands towers and flowers. 

There was a time of day,
When a crack in the cave's wall would disclose;
A slip of golden sunlight,
To the dark and moist cave floor below.

That slip of golden sight,
All too lovely to the eye,
Would grace that foreign glance just briefly,
And just a swiftly as it'd come,
It would say goodbye.

One day within the cave,
Where the girl knelt within her cold and dampened prison,
Chains rattled as a stiff body moved,
As the dawn -- over the unseen horizon -- had arisen.

Pale and sooty hands outstretched,
To touch that grace of glittering sun;
And as her body moved forward to grasp it,
Her dilapidated restraints had come undone.

The irons about her wrists and ankles crumbled,
And from out her confinement, she stumbled;
Into the green and vast out doors,
Where grass soon replaced the jagged, stony floors.

Out into the light, the girl at last emerged,
Only to within it, be completely submerged.

The flesh upon her body, pale as a cold winter's moon,
Was burnt to a crisp,
And with a gasp, her body,
Across the ground,
Was strewn.

Clawing across the grassy earth,
Back into the caves below,
The girl waited until her skin has healed,
Before giving freedom another go.

She was wiser now, this time,
And took her time with ease;
Until nothing else could stop her,
From following that warm summer breeze.

Into the world she went,
Graced forever with sun and light;
And she died peacefully in the forest,
After one fortnight.

Though the world right now may seem unjust,
Search desperately for your glimmer of hope,
Something you can trust;

And along your journey,
Going about your life how you must,
When it seems that the reality has lost it's fairness,
And that your mind is about it bust.
Just think of my story about a girl,
Bound in chains of rust.
