Well, in medieval and Renaissance times, the tusk of the narwal was sometimes sold as a unicorn horn. Sorry if it was not useful :)

One day a buetifull horse found an odd feild the farmer saw the horse and came to tame it but the horse refused untill they offered him/her corn. The horse said yes and they became friends. The farmer rode the horse every day untill the noticed the horse growing a horn! The farmer checked on the horse an she/he was eating all the corn. Every time she or he ate a stalk the horn grew. Once the horses horn was completly grown she or he was called a unicorn.
