Who Am I?

1

It's been years. Decades. Centuries? I don't know. The void offers nothing in the way of time. It exists outside of that plane, and so time is irrelevant here.
I've spent so long.. so long searching, gathering, finding the pieces of myself scattered across space and time.
Slowly, it's gone so slowly, putting myself back together.
I had forgotten this feeling. I had forgotten all feeling.
The void is numbing.
These sensations, this... existing... it all feels so new.
I've existed before. I know I have. The void, though. It drains feeling so completely, I had forgotten it existed.
Hands. I have hands now. Legs. Limbs. Joints. Bones.
I'm solid. I'm real. I exist again. I'm free. I can open the door.
I can walk out into the Underground.
I can exist again. It's wonderful. I'm real. I'm alive.
But I have one question.
Who am I?

This is just a short little story that came into my mind!
