The Baronial Historian.
The Historian is responsible for recording the history of the group.
It is possible that he might maintain meticulous records, organized boxes of documents covering membership, the minutes of meetings, and officer’s rosters.
Whole cabinets of historical minutiae including event flyers, photo albums, officer’s reports and what-not stacked to the ceiling in several large dusty rooms may represent the continuous history of the Barony from the dark recesses of antiquity to the present day.
Magnificent sheafs of aging paper including ancient court reports, changes to kingdom law affecting the group’s status, and newspaper clippings may be at his fingertips.
Or pretty much anything that he feels like tossing into a box behind the sofa.
Your Historian is THL Ilya the Wanderer.
