To all who may read these letters do We, <King> and <Queen>, by right of arms of the realm of Artemisia and of all Our territories King and Queen, give greeting. Whereas Our subject <name> has twice ruled as Queen in Our realm (by her valor and skill/by the valor and skill of her champion), it is Our pleasure to elevate her to the rank and station of Duchess. We do further affirm her right to bear arms by Letters Patent in the Society for Creative Anachronism, without let or hindrance, said arms herein more plainly described and depicted to wit: <blazon>. In witness whereof We set Our hands and cause to be affixed the seal of Our mighty Kingdom this ___ day of ___, Anno Societatis ___, being the year two thousand Gregorian.
