Original idea by only me

I came up with an original idea for a story.

It’s about putting leprechauns with vampires 
Mixed breed 

Here is an insert 

Leprechauns were a bloodsucking greedy creature that stole other people’s money and hid it in a black caldron. Leprechauns were called chauns because they coned with with a charm. Most mortals see gold or anything shiny and they want to pick it up. But it’s a trap. You cannot steal or borrow what is not yours. Once the onlooker even touches the gold, it is the time the leprechaun will spring out of no where. They will bite. The human is drained of everything and they disappear as though they never existed. Do not touch a leprechauns gold.
