Ambrosius Letter to Harco

Salve Sodalēs,
I, Ambrosius ex Verditius fillius Galfridus bid House Mercere salutations.
I write to you now from the recently established Covenant of the Long Mynd near Church Stretton in Shropeshire, Britannia, seeking assistance in a matter of great personal import to myself and my only surviving family, my younger brother, Llewys.
Due an unusual set of circumstances, it fell to me to raise my infant brother during my apprenticeship. He has been with me for these past eleven years, and is now of the age that we need to seek a tradecraft for him. After much discussion of the options, and a fortuitous visit by one of your Redcaps, we have come to the agreement that life as a member of House Mercere would best suit a young man of his talents. I write to you now, seeking guidance on how we might best prepare him to apply for membership in your house as a Redcap. What would it be best to school him on? How might he learn more of your House, its traditions, and its people?
I offer my more sincere and heartfelt thanks for any assistance you can provide in this area, and look forward to the day that Llewys may stand proudly among your ranks.
Vale.
