As a young kid i always thought it would be astonishing to be immortal and never age, as i grew and matured i never lost that thought i just looked deeper into it, i found out that being immortal and never aging would be a nightmare, you would have the power to destroy worlds and make all tremble in fear as the bow to you Superior power, But I've learned this world much to well, we don't bow to anything that slithers its way through our defences, we stand up despite our size, because what I've learned is that every being on earth has someone, at least one person who is their world and they could never conquer that, being immortal would be a nightmare
Imagine that you have just destroyed a whole city, among the wreckage is one person, she is scared and frightened, bruises and scars and dirt all over her body, shes weak, her bones are about to give in, you can see that she is injured, there is blood dripping from her head, slightly oak-ed because of the fire and wreckage around her, you can't bare to look but you can not bring yourself to looking away, you watch in horror and pain as her knees give out and she trembles to the ground, time stops for a moment, one of the only people you loved and lived for has just died in front of you.
You are mad at first, you don't know what to do, your whole world has just been destroyed right before your eyes, time has still stopped, tears running down your face as you look for hours and the body of one you loved and now you have death running through your head, her coffin is on your conscience, you rage, everything around is a blur, you are moving too fast, adrenaline is surging through your body at what feels like a million miles per second, you find a gun on the ground and cock it, you put it to your ear and your whole world is slowed down and you remember your whole life, how you became immortal, when you first met your world, everything is all summed up as you pull the trigger, the bullet slides right through your ear hole, it enters your brain and your life ends,
the only way to kill a immortal is to kill his world, at that point he shall see no reason to live and the immortal shall have nothing to be immortal for, the story is he went crazy with power, he wanted to protect his loved ones from everything, but he could never protect them from himself, and thats how he would die.
Protect your loved ones, immortal or not but they are all you have i certainly know if i lost all of my loved friends in one day, i would kill myself that day, cause i am nothing without them.
