Dear madam Shandara,
I hope this missive finds you well. My name is Desmund Tar, and I hold the position of captain within the Arcanist branch of the city guard's investigative division. I have heard a thing or two of your prowess within the field of enchanting, and would like to offer you a commission designing a new tool for me and my colleagues. As the details of this matter are somewhat confidential I cannot go into more details in this letter, but if you are interested in taking this commission you can come visit the Crown's gate guard precinct to meet with me in person.
Regards,
Captain Desmund Tar, city guard 1st investigative division, arcanist branch
