We took the shards of Frostmourne nowhere did it say the lich king had anything to do with it after the raising after all what DK cant rez a fucking undead but it took something special to raise a hero!
Everytime he rezed someone he used his sword which we now have in our possession.
So you are saying that what we did was just trimmings and it was the lich king doing all the rezzing all along? That he can magically put his resurrection powers into anyone and we just wave a worthless pair of sticks?
So those swords are meaningless is that what you are saying?
