This poem was modeled after "Stopping by Woods on a Snowy Evening" By Robert Frost.
I think it's an Iambic tetrameter with an ending rhyme pattern of AABA BBCB CCDC DDDD.
This is a short poem about Riku and his struggles in KH:CoM.
My Heart, My Twilight
In the dark of light I'll see it soon
The days and years over the moon
A place and time, a moment of sight
A voice that calls, with a soft sweet tune
I'll take up arms and begin to fight
For I'll never give up finding my light
I seek the sounds I want to hear
The daybreak I know is always in sight
The time has come, it's close and near
It would be useless to idle here
I keep going up, the stairs still winding
Here losing is finding, it's all so clear
A light so cold, a darkness so blinding
The darkness is all I could be finding
And between two paths I will be deciding
It's the middle, the Twilight to which I am siding
