The society of thieves and assassins under the command of the Qu'el'velguk are a powerful force in the House. This network serves the Ilharess as her personal tool for disposing enemy leaders, gathering information, and keeping tabs on the Drow of the House. Little goes on in the Qu'ellar without the Qu'el'velguk finding out, and this gives the House Assassin a powerful position. The Velkyn are among the most feared force at the command of the Drow and when they are dispatched, little can stand in their way.
