A new chance far too late

I slowly regain conscious, but there's only darkness around me, I thought to myself: "huh, so this is the afterlife, too bad those bastards aren't here to share in the joys of it with me... ah god, I'd given anything for a chance to get back at them, I won't let them get away with it" truly, the last thing I expected was an awnser... "Interesting" the word echoes in my head like a thousand drums on my ears and a million of needles on my skin, I lose conscious again but my mind is awake, awake in a feverish dream, an endless darkness extends itself infront of me, not like the one before, I could feel the ground bellow me, I could feel myself but here... there was nothing, it felt like an eternity could go by in the blink of an eye, or in this case, a thousand of them, points all around me, looking at my soul from every direction, a voice that sounds distant and at the same time like it was coming from inside me says: "I can give you a chance for vengeance, all I ask in exchange is that you help me get back out of here" I look around and I noticed a gauntlet on my arm, with a black gem on it, but as soon as my eyes lay on it, it opens revealing a yellow and red eye looking back at me, I hesitate for a moment, but I already made my choice, as soon as I think about saying it all the eyes seem to fly in front of me creating a pitch black form, it then extends a hand to me, I grab and shake it, and as soon as I feel it's touch my conscious jolts awake with flashbacks and images, images of a war against a unfathomable creature, of heroes chosen by a god destined to destroy it, but they were weak, they only managed to seal it away, my eyes are dragged as the images flicker on my face and are all twisted into a small dark orb that flies to my arm, I look around after I regain control of my senses and sure enough, I'm again at the dark, but this time a solid dark, there's ground underneath me, there's air on my lungs, there's pain on my bones, I wander lost for a few seconds, I look at my arm and sure enough theres a gauntlet on there with a black gem, I'm not sure why but I already know the way out, I stumble on the darkness for what felt like an hour until I finally reach an exit, there's a human girl with a backpack setting a campfire, as soon as I step out she rushes to me and grabs the gauntlet on my arm, I think about retracting it but something tells me she's going to be useful to me, she examines the gauntlet for a moment, I think she is murmuring to herself but I'm still drozy form everything to understand her, she then looks at me with an awe in her eyes that looks almost unnatural, I got something very few can say they had, a second chance, and I'm not going to waste it...
