There once was a greedy man named John. He lived in a small village. To be truthful though, he didn't care much about what happened around him, nor to anyone. He was cursed because of it, so he felt. Inside him, he knew it was just carma though.
One day, one of John's neighbor's trampled on his lawn, and he was furiously calling his name.
"What do you think you're doing?!" John barked. His neighbor complained that he was being too noisy by nighttime, throwing some of his trash in his (the neighbor's) yard, and was just a snooty grump.
John became so angry with his neighbor, that he grabbed him by his neck, and choked him to death. After that, though, a large deity appeared from thin air.
"JOHN! YOU HAVE BEEN VERY HEINOUS IN YOUR LIFE! AS PUNISHMENT, I SHALL CURSE YOU, BY TURNING YOU INTO A SHADOWMWN, AND YOU WILL REMAIN IN THAT STATE UNTIL YOU CHANGE YOUR WAYS!!!" The deity bellowed.
Just then, John went, in a sense, invisible. All that remained was just a shadow. There was no body, no spirit, just a plain-and-simple shadow. On one side, he could move a little faster. Another side, though, to it was: He couldn't touch anything without passing through it.
All John could think of to say was "I suppose I deserve this. Better make the best of it while I can".
