Abyssal widow

Abyssal widows were servants of Lolth, her handmaidens and midwives. They guarded the gate to the Demonweb Pits.

Description
They were female drow looking entities of astounding and unblemished beauty, with eight spindly arachnid legs protruding from their sides, keeping them from touching the floor. The wizard Pharaun noted that their beauty was transfixing, to the point that he thought the first of them to appear to be Lolth herself.

They could also hung upside down from the ceiling, just like a spider would.

History
Even among drow priestesses, they were a myth, and others didn't even know they existed. They acted as handmaidens (presumably along the yochlols) and as midwives and guardians. Their existence was prophesied, and when the Silence of Lolth came to an end, they came into existence. They were seen guarding the gate from the ruined temple of Lolth in the Abyss to the new Demonweb Pits.
