I enjoy getting to write letters in period style, the formulaic method that was used makes it easy to transform an invitation to the Crown into something that adds to the game.
Here are three letters I’ve written in the past by taking letters from about the same time period and utilizing the same formula in an SCA context. The letters were then given to those with a much better hand than mine to write out.
An invitation to the King and Queen of An Tir to attend an event I was running:
To Ieuan Dei Gracia Rex An Tir et Viscomes Tir Righ et dominus Aquilon, and Gweneth Dei Gracia Regina An Tir et Viscomitessa Tir Righ.
Your faithful subjects of Lionsdale wishing to observe their oaths and the fidelity due to God and to you, wish health, and tender their lawful service with all respect and honour. To this we desire for you to attend our Winter’s Tourney the Saturday following the celebration of the Presentation of our Lord (February 4th AS XLVI) that we may render our thanks unto you for being our sovereigns.
At Lionsdale, on the 15 day of January in the XLVI Year of the Society.
Lord Tomas de Courcy
