A race in my books is made by a deity recrafting a human. This recrafting is brought on by killing a dragon and infusing the dragon's essence, death energy, and hate into the human. If it works, the dragons essence and hateful energy will be dominated by the "human" and will fuse mutating the human's spirit and eventually body and mind into something inhuman. This race are called in the oldest tongue Vagarii (the champions), they are known as well by the names demiduur(hunter), emorii (dead thing), and dragon slayers. They are prone to heroics and seeking out rivals and adversaries. They lack all but the most primal emotions. They tend to have a condescending edge. They have fantastic speed and reflexes and are unable to be killed by age, sickness, and most means given the nature of their curse/blessing binding their soul to their body. They act like a cat in a humans body oftentimes resulting in acting superior, predatory, and often shy and observant of things they distrust. People who become this creature do so usually to get revenge or to protect someone. Their motives for originally becoming this creature are usually undone in the process. This creature is incapable of letting the blind hate of vengeance obscure the real story from their sight and they come to understand very quickly that all which is human dies and trying to protect someone is only a temporary fix to a long term issue. They rarely form attachments to anything outside their own breed. They have close familial attachments to their own breed and are incapable of turning on each other as humans do. If they fight it is due to believing they are helping the other to not make a mistake. Would you call this a blessing or curse?
