Nightsisters

An otherworldly league of female assassins made up entirely of Drow. Their origins date back to the first Drow and early worship of the Spider Queen Godd, Lolth. The first Nightsisters were born from the ichor that Lolth shed from her many legs and went on to kill in her name for centuries. In Elvish culture, it's believed that if one prays to them to take a life that they'll do so at a grave cost. They are boogeymen and tales told to children to make them behave lest the house of Nox and Shadows takes you away. They are led by matriarch Desdemona Nox.
