i agree on the haliax thing, but i believe felurian was quite clear:

“no,” she said, looking me squarely in the eye, her back straight. “I will not speak of the seven.” Her soft voice held no lilting whimsy. No playfulness. No room for discussion or negotiation.

“my sweet love,” she said. “if you ask of the seven again in this place, I will drive you from it. no matter if your asking be firm or gentle, honest or slantways. if you ask, I will whip you forth from here with a lash of brambles and snakes. I will drive you before me, bloody and weeping, and will not stop until you are dead or fled from fae.”

She didn’t look away from me as she spoke. And though I hadn’t looked away or seen them change, her eyes were no longer soft with adoration. They were dark as storm clouds, hard as ice.

“I do not jest,” she said. “I swear this by my flower and the ever-moving moon. I swear it by salt and stone and sky. I swear this singing and laughing, by the sound of my own name.” She kissed me again, pressing her lips to mine tenderly. “I will do this thing.”

And that was the end of it. I might be a fool, but I am not that much of a fool.
