Dragon Fangs
These two swords like weapons are made of the fangs of an ancient dragon. Two hundred years after Atlantis was destroyed, an ancient dragon that was dieing of old age removed two of her own fangs just before her death and gave them to JD.
These swords are living weapons, named Yin and Yang. Both of them posses the knowledge and wisdom of the dragon that gave them to JD, but their personalities are absolute opposites. Good and Evil. The swords always keep together, and it is not possible to only posses one, or to lose one. At least if you want to posses anything but normal swords.
When both swords are present, they have the ability to communicate mentally with their bearer. While their intelligence is not known, they posses the wisdom and knowledge of a dragon. So while they always try to influence their bearer, their advices are based on knowledge and wisdom that few beings equal.
