Drow

Drow are born of at least one elven parent and one who does not have elven blood; however, not all half-elven children become drow. Only if their conception breaks the oath of the parent or if the other biological parent is of infernal nature is the offspring destined to become a drow. Signs of this change usually occur in late puberty, around 100 to 120 years of age. Changes may continue throughout the lifespan of the drow, and they usually do not live the full lifespan of an elf. The elven family cuts all ties with the drow child and with the transgressing parent. Occasionally, a fully elven child will become a drow due to their own transgression or that of someone very close to them.
