Rabastan almost smiled. Months? Such dedication. Perhaps he would give her at least the books that would lead to the book in his pocket. Perhaps.
Rabastan sat with her and returned her bag. When she pulled out the parchment, he leaned in close to read it over her shoulder. Wormwood, essence of murkroot, coriander, marjarome sap Hah. They didn't even notice the various nightshades or the essence of Gorgon root. "Mhh, well, at least we have somewhere to start." He extracted two of the books from his bag, "Here is Moste Potente Fungai and Darker Purposes and Cursed Potions the latter published in 1032. I doubt whatever source you have had these in its possession. I had to comb very nearly the four corners of the world for these copies."
He paged through Cursed Potions noting on a scrap of parchment the several potions that were similar to the one he had concocted. Every so often, to continue the ruse, he would look at the list of ingredients, sigh over the matrix and shake his head in frustration.
