I get a cursed sword

Being told what to do is not a problem.But ordered around by God's for your entire life is something you never do.

My name is pelo. I come from a family of travelers in which is something I would be come some day.Right now my dad is traveling across the world.I never met him though while my mom who takes care of me is a nurse.I am a girl who is 13.I have ADHD and ADD.I also weird paranoia mental problem where the supernatural then it disappears.I live

with my mom and my grandad.i love my grandads stories that he tells me everyday.my favorite is the adventures of Merlin and king Arther.And now I'll tell you my story.I was having a normal day at school in the city of Vermont New York. my class was on a field trip to a museum. As my class was in the Greek and Roman section, I saw a boy about my age mysteriously came out of nowhere In another room looking at egptian heroglyphics.Then he grabbed a rock from his jacket pocket.then snuck out of the group and and walked towards him."hey" I said. He jumped and turned towards me confused. "Is there something that you need " he said. " Just wondering what your doing" I said. He put the stone glyph on the stand and put his hands in his pockets. "Nothing"  he said casually." Just looking around". "Ok "I said then I turned around slowly, suddenly he pushed me grabbed the stone glyph-and vanished.As I looked around if he was around I saw no one but me and my class in next room.I started to wonder y alarm go off and how did vanish with no exits around.The more I thought about it the curious I was. I then went back with my class if nothing happened.As my class was on our way to school on I saw a what looked like a pale middle aged man staring at me from my bus window. He then did weird hand signals and mouthed something.i turned around and see if anyone else saw but it was only me. I looked back at the window and saw the boy from the museum. I tapped my friend John that was sitting by me. "He stole a stone glyph from the museum" I said pointing at the kid. "Who in their right mind would steal a glyph" John replied "what is he gonna do summon a demon".The bus had then came to a stop and was a block away from school."well I'm gonna go after him" I said back.Then I ran of out the bus and ran towards the kid.He scared and said "what are you doing here run". "Not until you put the stone glyph back" I said."this not the time run someone is after me!" he said pointing at a crowd that across from us. Then I locked eyes with a man with a dog. Then for a moment I saw a ceberus by the man. The kid pulled a bracelet out of his pocket and I then saw the stone glyph in his jacket pocket. I then grabbed the glyph and ran. I looked back and saw the ceberus was following me and I started down a few streets and suddenly ended up at the museum. I looked around and the dog was gone I then looked at the stone glyph.One side had a fleur de lis symbol while the back had a omega symbol. As I made my way in the museum the stone glowed and stunned my eyes.i covered my eyes and went towards a wall.As I recovered, I found myself holding a 6 foot sword and through a body of a middle aged woman.Running in the museum was the mysterious man with  the dog. "Hecate" he said

" you killed a goddess but how a mere human can do that". Then looked at my sword."give me the soul caliber."
