There's no direct link to the Scots, simply because the subject is complete fantacy. However, last year we were in the new Scots' corner (the old one having been sequestered by the mods), and we just started discussing a theme for this year. D&D was discounted, as was LOTR (done to death) and GoT was suggested so we all thought it a great idea.
As far as kit goes, Saxon or Viking will mostly fit the bill, but because there won't be public there, anachronisms will be welcomed, and probably laughed at. The aim being to have a damn good laugh. So, plastic or foam swords are fine (also real ones), and we might even get to kidnapping someone from naughty corner and hold them to ransom....
