From birth half-drow progress through early development stages quite rapidly. Motor skills and language skills follow the ability to walk, and by their second year, they could easily be mistaken — drow-like features notwithstanding — for a human eight-year old. Sexual maturity, however, will not occur in half-drow until they reach their mid-twenties. As they approach middle years many begin to experience hair loss, but do not wrinkle, as humans do. Instead, they experience bone-loss as their other elven races do. This often leaves them frail in their elder years, and prone to debilitating bone breaks. Though violent deaths often come much sooner for half-drow, death in the form of advanced age usually comes between 150 and 180 years.

Half-drow share the chaotic bent of their drow heritage. Not inherently evil by nature, half-drow are often subjected by their drow masters to cruelty as Lolth demands. Their lot is perhaps worse than that of those the drow initially conquer, for they are not only subject to such torments by the drow, but also often reviled by the subjugates from which they sprang.
