Lolth

Lolth known as the Queen of Spiders as well as the Queen of the Demonweb Pits. She was the most influential goddess of the drow. Lolth was a goddess of cold cruelty not out of place in the darkest depths of the endless Abyss, reveling in betrayal and bloodshed and toying with everyone from her minions to her victims. She not only enjoyed, but thrived upon torture, destruction, and death, whether personally performing it or causing it. Every interaction was ultimately done with malice, ill will seething from her every move, and even those who knew her well could be surprised by just how deep her viciousness went.Her malevolence could be compared to the rage of the brutal orc deity Gruumsh. the Spider Queen wanted surface elves to be sacrificed by her worshipers. Lolth ordered her followers to keep drow society stagnant in every regard.
Vhaeraun's masked traitors, clerical spies Lolth had mistakenly believed members of her own clergy, were enough of a problem that she considered their discovery, and warning her clergy of their existence, worthy of her personal attention. Indeed, Lolth, who normally gave worshipers of other drow gods a second chance on being found out, made an exception for Vhaeraun's followers, who were killed right away.
