"Dear Thirron and Relem,
I have a job for you. I recently heard of a woman with valuable first-hand knowledge of a unique world, not located in our multiverse currently residing with the Summer Queen, Titania. She'd fit perfectly in my collection. While my first attempt to acquire her failed, she and Titania decided to have her leave for the Material Plane, somewhere in northern Medweda on the world of Sancstoryl. My influence in that world is limited, especially since my last warlock destroyed the tome that I predominately use to make more of them, but you two have acquired knowledge and knowledge-keepers from the Material Plane for me before. Should you accept, then I will give you a device that can detect the type of energy she radiates. It should help you find her. Bring her to me. I have a wonderful abode prepared for her, and with some... persuasion... I am certain that I can make her share her precious, delicious knowledge.
Accept this request, and I'll reward you with the usual lavish payment. However, should you fail... well, I hope you have some gifts prepared... Something that could fit nicely next to my last warlock's soul in the cabinet. She was fond of stuffed animals, so perhaps one of them might make her less... fussy. She sometimes makes it oh so hard to get a good night's rest, after all...
Best regards,
Nuferos, the Swamp Sage"
