You come from the modern world, the future as you could say. You have your own special powers and abilities.
You had made quite the name for yourself, everyone who lived in your city knew your face and name.
You knew a friend aswell who wanted to create time travel, you helped them build the machine. Everything was going perfectly and that's how you knew something was going to go wrong.
And you where right, one day you were fighting with one of your enemies that had broken into the lab you were working in. During the fight one of you ended up activating the machine and it ended up sucking you inside it.
The machine ends up sending you far back into the past. A portal opens up and you get thrown out, you hit the ground and role a bit before stopping.
When you get your bearings and stand up you realise your standing on a very high wall with a small village all the way down on the ground.
You have been sent back to the year 845 a year where your modern technology fossilis the technology of this era. Getting back to your original time might be impossible so it seems like your gunna start your life over from scratch here.
You just hope that people won't freak out and try and kill you or anything like that.
