Kingdom Hearts Riddles IV

[Pheesh]

I remember these threads so fondly from when I used to be active, and I remember they were a lot of fun. So I looked through the board and found the old thread, but I thought that this time last year might be a bit too long for a thread to be revived. So, let's continue on where this thread's predecessor died a year ago.

I'll start us off ^^

In darkness I begin,
steps taken into an unknown world,
leading you on a quest for knowledge.

Unlocked with perseverance,
I'm a reward for your determination,
Enjoy the images that you have earned.

Faces blur by us,
as the shadows surround us,
the familiar has been left in the past.

A countdown of destiny,
a glimpse at your journey to come,
in darkness I will end.

What am I?

Hopefully it's easy, but not too easy >_o Have fun guys.

EDIT: for anyone new, or unfamiliar with the riddles threads, they are pretty self explanatory. Make a riddle in any format you wish, make sure it's kingdom hearts related, whoever answers correctly takes the next turn (unless they waive their turn), and try to give other people a shot to have a guess.
