Half-drow

A half-drow was the offspring of one human parent and one drow parent. A half-drow generally had dusky skin, silver or white hair, and human eye colors. They could see around 60 feet (18 m) with darkvision but otherwise had no other drow traits or abilities.

History
Half-drows were often conceived when a male drow mated with one of his human female slaves or when outcast drow mated with surface-dwelling species.

Xandra Shobalar encountered a merchant in Mantol-Derith, ostensibly human, who was in fact half-drow. Perhaps indicative of the drow view of such things, she found his suspected nature to be appalling. .

Physical characteristics
Half-drows usually look more like the drow, than the other breed with which they are related. It is not unusual, however, that they have some characteristics of the other breed. If a half-drow is a dwarf to the other half, it is often smaller than most drow it's.

They grow up differently fast. It depends on which breed the non-drow parent belongs, so that the time of growing up can vary greatly. However, they grow faster than elves, and are also more fertile.

Culture
Half-drow have no real society. According to the drow, they have half the blood of an "inferior" race in themselves. On the other hand, most peoples can not recognize the difference between a half-drow and a drow.

They do not fall as fast to the evil, like drow. Their non-drow origins allow them to more quickly recognize that the drow only follow lies, and can more easily leave the drow's way.

On the surface, half-drows are usually not accepted, but many half-drows go to the surface just because they want to prove that they are different from the drow. They leave the underdark to become adventurers.

Half-drows who stay in the underdark try to spend themselves as pure drow, and can get in power. When they are discovered, they are killed by the priestesses of the Lolth because of their "weakness". If, however, they are not discovered, Lolth allows them to survive because a fraud that does not attract attention is a sign of power for her.

Abilities
Half-drow have besides the ability to darkvision, also very often abilities of their non-drow breed. Thus, half-drows that are to other halves are humans, somewhat stronger and more resistant than pure drow.
