Drow

In-game description:
"The Drows believe that any crime can go unpunished if nobody notices you did it. They value and praise perfect executions, and will reward those who plan accordingly."

The Drow Faction

Drow was implemented during the Underworld expansion (v1.2). It is the Evil Prestige Faction, and will only appear when playing an Evil Vanilla faction. The Drow player will be able to combine the 2 faction spells and all the 18 upgrades and from both the Evil Vanilla and Drow factions. Several of their upgrades relying on Royal Exchanges play evil with the faction-coin-heavy Goblin Faction.
