The Ancestral tome is a large, leather-bound book containing the entire written history the Celtic tribes of Northern Ireland. The book measures nineteen inches up the spine, thirteen inches in width, almost six inches thick, and weighs just less than thirty pounds. The edges and spine of the book are gilded with segmented iron, bronze, and nickel plates. Another iron plate runs across the center of the front cover, and cast into the iron are a variety of rune markings. The Tome is passed down from one Keeper to the next when the old Keeper either passes away or forfeits the rite. The next Keeper in line is named when they turn fifteen, at which point they study runology and they people's history. They do not typically become the official Keeper until later on in life. Ruarc however took over at age fifteen when he was named due to his father forfeiting the position. The Tome is filled with thousands of pages, and countless entries that have been added by Keepers past. Each entry is write in different styles, dialects, and handwriting which make deciphering all the entries a life long endeavor.
