You weren't the Hero, of course. The sort of soul upon whom the whole world turned, the handsome wonder who would set things to right, defeat the evil Empire and get to marry the charming princess once everything was sorted out, and the world was left in peace. Fate never bowed to you that way. No matter how you might have hoped for it whilst younger, you weren't the Chosen One.
But you were someone. You had your goals, your hopes and dreams. You were ready to fight for them too. True, you may not have been some sort of world conquering legendary protagonist figure, but you made your way in your world, and who knew? Perhaps one day, you'd get there, stand amidst the legends of your age. Everyone had to come from somewhere, right? Your future lay ahead, and things were looking good.
Only something went wrong. Something... strange.
You can't tell when, or how it happened, but things... faded. Dissolved, cut to black. Things weren't truly over, they simply... stopped. Events, time, places, people, there are none of these things here for you now. Just you, alone, floating in a sea of emptiness. Eternal, unending absence; of light, sound or even time. A void that most people couldn't even begin to imagine..
Yet in that perfect, unending emptiness, one thought echoes, returns to you, again and again, ringing out across all of infinity. Yours or another's, it makes no difference, as it pounds away at you, again and again, no matter what you do..
You are alone.
