Society Earl Marshal
It seems this is coming up again, perhaps due to a resurgence of interest in rapier fighting from those gentles living in Calontir.
Yes, according to the Society Marshal's Handbook, you may not issue authorizations to persons residing in other Kingdoms unless they are considered a member of the issuing Kingdom (which I know of 1 or 2 cases, but it is exceedingly rare).
There *is* however an exception to this rule. The details of that exception are spelled out below. What this means is that a subject of any Kingdom that does not allow rapier combat (currently only Calontir) may seek to authorize in rapier combat under the rules of another Kingdom.
Note that it is from only *one* other kingdom (they can't get light rapier single blade from here, heavy rapier case from there).
The only requirements (beyond those normal for a rapier authorization) are that the "sponsoring" Kingdom's KRM track said individuals by name. To authorize someone, a KRM needs to be willing to back up whichever marshal said "they are safe". So, there's no border requirements. A Calontiri could have a Lochac authorization, assuming they could somehow convince the Lochac KRM that they pass said authorization.
I expect most of these authorizations will come from the Kingdoms that border Calontir (such as the Middle or Ansteorra). But if someone moved to Calontir from Atlantia, the Atlantian KRM could allow him to keep his authorization card simply by taking on the slight administrative burden of tracking it. All other normal authorization and re-authorization processes apply.
Reminder to KRM's - I need you to keep track of these fighters by name.
You or your Minister of the Lists should have all the pertinent information
(address etc...) in your normal paperwork. I only need you to report to me on total numbers "sponsored".
