Pre-Face:
There are two ways to earn another member of the immortal damned. First, there is the traditional way: the biting of a mortal. This enables the bitten mortal to become a vampyre, but banishing their soul to the bowels of Hell.
The second act is of birthing a new vampyre from two already immortal parents. The child borne will grow as a common mortal until they reach the age of their closest ancestor that was bitten. An example would be if the child's father was bitten when he was thirty years of age. This would mean the child would age until the age of thirty years, and then stop growing for an eternity.
There is on a rare occasion that a female mortal bears I child with a male vampyre. These kinds of children are known as abominations and are destroyed as soon as the Grand Council deems is appropriate. The mother is executed and the father would be severely punished. Such known incidents have occurred three times. None of the children have lived past their first Birthday. Little is known about how a half-blood's life would go.
