I grew up with my father,
he was a powerful adventurer,
he wanted to fight for the country he loved, and died because of it, the last thing he gave me a was a knife,
for regular people its just a knife made out of adamant, well yes, a knife like this is pretty rare, and very hard to break, but for some reason this knife is only conductive with my magic, I didn't know why, but maybe my father left this knife for a reason...
