Inevitable

Hello and thank you for taking the time to look at this creepy pasta. This is my first attempt at making a creepypasta, so any critique is welcome. Once again thank you, and please enjoy!

I will leave this short, as I only have hours left before I most certainly will meet a terrible fate. Allow me to introduce myself. My name is Harold M. Sanders, and I collect... Items. I will cease further detail into what said items are, so no other generations will be put at risk by that accursed thing. Before I continue, I must stress that you should not conduct further investigation about this said item, as it will cause the apocalypse. This all started to what most people remember as about five days ago. I had been crossing the lands in search of a new item to add to my collection, when I saw it in a window of an old gravekeepers house behind a small village. When I asked the man about the said item, he told me what I thought was a convoluted story. He rambled on and on about how a demon possessed it, and would do this and that, probably to make me change my mind about buying the item from him. Being one to not take no as an answer, I convinced the man that I would go and burn the item so it would be of no harm. After about an hour, he reluctantly agreed. I walked out of the village, the item in my backpack, and set off to my shop. After a day of having it, guilt started to set in. I couldn't go back and give it to the old man, oh no, not after working so hard to get it. But I couldn't also burn it, as burning items was against the law in those lands. So I set off towards here, unknowingly causing my, and many other people's demise. About three hours later, as I walked through the forest, the item tucked inside my pack, something came from behind and hit me blunt in the head. Sometime later, I awoke. As I got up, I realized something. My pack had been ransacked. But surely nobody would find that. After all, it was hidden very well. But as I looked, and looked again, I finally accepted it was gone. Many things ran through my mind, when I decided that it most likely would pop up in one of the nearest town shops, as there was really no other logical reason for stealing it next to selling it. When I got into town, I searched in every store, checked every alley, and asked everyone, but I had no luck. I checked into an inn inside the town, but slept little that night as it haunted my dreams. I had given up on finding it, when it popped up in my mind. I got rid of it! I felt something I had not felt in a while. I felt relaxed! However, there was something that I realized when I looked up. Everything that old man had told me was true. What it was, I cannot explain. All I know is that it had been coming closer each day. How could I have been so naive? What happened up there that night, I know not. All I know is that everything reset, like a clock, to around the time three days ago when I first entered town, even that thing that had been so near was back to where it was then. Nobody remembered the past, or future events but me and him. I was inside the Clock Tower, when I saw him. What had happened to him, or how I healed him are still a mystery to me, but that thing he described was what I had feared. The time has reset twice now, thanks to him, but I fear he is only delaying the inevitable. I should have listened to the man. I should have never touched that accursed mask.
