"Black Widows are the caste of mind-Healers," Karla explained, "so first and foremost, we learned about the mind, how it worked, how it failed, and how to put it back together again."

"But we also learned how to weave tangled webs, how to create illusions, to tell true dreams from false ones, and a lot about poisons. There's a lot that goes into Black Widow training, really."
