Honoured Sir,
Allow me to introduce myself. I am Tipperrary Washington Deeplington, priest in service to Calladuran Smoothands, and a fellow gnome.
I would like to extend to you this invitation. Free membership in the newly formed United Union of Gem-Cutters and Gear-Makers of the Greater Dunwarren Area, excluding Surrounding Environs, local 103.
Understanding of course your desire to leave this cavern, and your work towards getting that device of your operating, I feel that it is a sound business decision for you to join the union now, to protect your business now, so that you enjoy a secure and safe stay while you are here, no matter how short term it may be.
Respectfully yours in Gnomehood, Tip Deeplington
