Graham's persona is currently indeterminate, though he is leaning towards 13th-14th century English.
What history? He's still “totes newbsauce” despite having earned his Award of Arms.
His son is Ivan Day.
Graham is currently uncovering the secrets of kumihimo. He's successfully avoided being forced into any sort of armour at the time of writing, though has been sighted on Archery and Thrown Weapons ranges. There is a scurrilous rumour that he may be involved in some capacity with unlicensed wordsmithering, and will likely soon be investigated by the Scribal Constabulary and summarily pelted with used inkwells.
