תרגום - אנגלית-נורווגית - Dark Prince of Cold Blood. Raven. Cross....

Please.. I have to know the diference between "Raven" and "Crow".
I know that they both are black birds, but I must discover the difference between then.
Thanks a lot.

The words are choosen in order to suit the theme of witchcraft. Otherwise they have a lot of synonyms. Distinction between Raven and Crow has been done.
