I think I can second the basic idea of scrolls adding flavor to the game. However both methods of obtaining these and their usefulness in-game seem to raise a slight doubt. But that's just an opinion.
One (more =) ) crazy suggestion from my side, involving scrolls. A dedicated scroll writer (skill, say, Teaching) can create scrolls of enchantment. Then, at some custom workshop an enchanter (I don't know what skill could this be) can with some luck enchant wands - take a scroll and a base lower-class (standard Forge issue) wand, then substitute it with a higher class wand (should be modded into item_weapon_wizard, but not into entity_wizard to make it impossible to be produced at Forge). Sadly, quality modifier will be lost =( However, with master writer and enchanter you will not need a master smith, so if metal is scarce and usual weaponsmith training is thus hampered, you can train enchanter instead.
Edit: in this respect a chance of successful enchanting can be made rather low, so that enchantment process would be long, resource-consuming, but high reward yielding, justifying a need for master enchanter (and writer). A grandmaster mage with armageddon wand and a dozen grudges - death to invaders! ...just don't piss off that guy, watch if he has good enough rooms and food and has no contacts with fellow wizards he doesn't like very much =) Personal dining room, or even personal tower!
