Right after the millennium war only one race was almost wiped out from the planet unfortunately humanity as resilient as it is it stood no chance against the dragons the angels and the demons and the strongest of all of the four clans the Dragonic Assassins they are the most fearless that there are because they can attack while you sleep or poison your food or drinks thats what makes them less menacing however their main strategy is head to head marcial arts combats so far no one has been able to defeat someone from their clan not even their weakest assassin was defeat even after two hundred battles he is still undefeated .
