Historian has scholar, armsman and... something else, I forget. Scholar uses those tablet fragments and relics you find to make potions, wall paints (apparently) and books/scrolls. The books have varied effects, like increasing critical success chance for professions or lowering skill costs. This is all taken from my memory of the brief scan I did on the wiki, so check that out to see if it's got any appeal to you.
Edit: Farmer, weaponsmith, Scholar. The books scholars make are loremaster equips, and the scrolls do good things for crafting critical success rates. They also make scrolls of battle lore, whatever they are, and potions, dyes, bombs and paint. Definitely paint.
The only wiki the NHS filters let me access is crap.
