There were times that Bartleby almost wished more people were accustomed to necromancy, if only so that he didn't have to go through this introduction every darn time he sent a zombie in for a meeting. "You'll have to excuse me, but until we hammer out all the details of my...shall we say tutoring...I'd prefer to remain at least a slight form of anonymity. I'm well aware that once lessons begin I'm to make my appearances in person, but I'm just a little bit cautious." People in the blood magic circle tended to not be exactly the pinnacles of trust and friendship, but if deals could be made with even the devil then arrangements could still be made.
The speaker let loose a little chuckle, "As you can see, I've already got a few skills of my own but I'm more than interested in expanding my repertoire. Speaking quite frankly I was drawn to your ad because I've great need to learn the intricacies of blood magic, and I would love to enlist your services to teach me." Were he out in the open he wouldn't dream of voicing such an offer so plainly, but spoken through the lips of someone that couldn't be traced back to him gave him just a little bit more freedom. "Also, might I add that you have just a lovely accent."
Hey, you can most certainly catch more flies with honey than you do with vinegar, and Bartleby had more artificial sweetener in him than a Splenda factory.
