All destroyed in the great war against OP weapons. A lot of people named 'Mary Sue' had most of them. Usually, those weapons mementos from their dead parents. Nobody knows how a dragon/human/ogre/phoenix mix came to be, why they always look like human women, nor do they know how they got their hands on such powerful weapons... nor can we seem to recreate them. It is unfortunate, but, perhaps, in some other universe, these weapons still exist.
