The Key To The Door That Leads To The Way

White surrounds it entirely
A special key shows its face
It's said to be a white wolf
Which bit my blood and made it race
After dissolving something opens
Vision improves for those to see
The right type of eyes can see the future
I'm hopeful that's where I'll find me
Staring outward into a corner
Straight ahead while looking back
There's a perfect circle made of blue
So i enter its center
Made of black....
