Disclaimer: I do not own Harry Potter.
I swim against the current. As it is this realm's Veil, it flows inward, the souls of the newly dead flowing into this realm of the dead.
The closer I get to the Veil, the stronger the current. But I contain within me the power of thousands of dark wizards and magical creatures. A simple thing like the boundaries between the living and the dead won't stop me. Not when the many names around the world they called me when I roamed the living translated to God of Death.
I am the Death Eater, and I have been away from fresh souls for too long. I hunger for a new feeding ground. Where I can feast on the souls of evil. Where I can punish those who are so like the ones that murdered every living connection to humanity I had.
Neither this Veil, nor Death itself will stop me. I may no longer be able to call myself Harry Potter in this monstrous form, a cross between dragon and dementor. But I will not stop trying to save others. It is the only thing I have left that separates me from the monsters within me. The only thing I still know is the right path. Without that, I will lose myself in my beastly instincts, burning and consuming everything around me.
I need out. And I need to get back to my saving people thing. I can't do that if I allow myself to stay dead.
As I near the Veil, I can feel the hands of the dead clawing at me, trying to hold me back, or maybe take them with me. I shrug them off, as the dead don't command the Master of Death. The Veil glows with the power of souls flowing through as I crash into it and burst forth in agonizing pain of ripping myself from the clutch of death.
Immediately I stretch my wings and roar as the sensations of the living flood back into me. And the hunger returns.
