At the scriptorum, there should be an entry for "write histories" to make a book specifically set up to function like a history engraving. Books about histories seem like such an obvious thing - You could have whole libraries of just historic documents.
Thats a great idea. A book could also have multiple historical entries with more descriptive text.
For example a statue is something like: This is a statue about Urist the Dwarf and Puff the dragon, Urist is standing over the body of the dragon. It relates to the slaying of the dragon called Puff.
Whereas a book might show something like: This is a book about Urist the Dwarf and Puff the Dragon. Urist was born in XXX and was xx years old when he met Puff the Dragon. Puff was an Ancient Dragon, countless years old.
Urist encountered Puff the Dragon and ran him through with his Steel Long Sword. Urist then stood over the Dragon in victory.
Urist was a hero of the Blazing Coppers.
