Chrono Keeper

Knox was two steps away from a kleptomaniac. He couldn't help the fact that the broken pieces of tech from the old world were simply too enticing not to take. That was how he ended up with a watch that was definitely not his, and had a strange penchant for drinking blood. Little did he know that taking that one watch would change everything and thrust him into a world he could've never imagined.

But despite the world being new to him, the people inhabiting it were far from new to him. What exactly did that mean for the boy’s fate? Only time will tell.
