"Dhampyr
A mortal offspring resulting from a union between a mortal woman and vampire male. Most people believe that vampires cannot procreate this way, this is false. It is rare, but occasionally a child can result from such a union.
Nature does not ignore the fact that the father is vampire. The melding of these two worlds of living and undead gives the dhampyr many strange abilities given by nature as a defense against vampiric influence. These abilities include quick movements, enhanced senses, longevity, unnatural charisma, the ability to resist the vampiric nature that is ultimately part of them, the ability to recognize those of vampiric blood, and the ability to withstand other vampires. These special abilities are what make dhampyr naturally effective vampire hunters, and can make their lives dangerous. Not all dhampyr become hunters, they may just as easily assume the life of the mortal parent.
The vampiric powers of the dhampyr are powered by blood, just as the vampiric father's. If a dhampyr feeds completely, a full meal, then the vampire part of its heritage will come to the surface and take over, they will suffer from bloodlust. This does not make them vampire, they remain mortal.
There are some dhampyr, however, that are able to use their vampiric powers without relying on blood. These are rare form of dhampyr, they are not hampered by the need to feed when the bloodlust calls them. The ability to withstand the call does not weaken this form of dhampyr in any way, they are still as dangerous and effective with their inherited abilities from their vampiric father.
Since dhampyr are mortal, they are not affected by the sun anymore than any other mortal would be. If they have tasted blood, the brightness of the sun will make them uncomfortable but they do not suffer as vampires do. They have no need to fear the sunlight. Dhampyr have at times been called "Day Walkers" because of the tolerance to sunlight.
Dhampyr who are embraced become vampire. They lose all dhampyric traits they had before the embrace, including the ability to withstand the sun.
Upon reaching adulthood, the dhampyr will begin to have dreams. In these dreams, they will see images of their father. These dreams serve to bring the father and child closer together. The dhampyr will be drawn to find the father and will eventually seek him, at times to kill their sire.
