A few years back, there were some threads offering a thing a day for November. I think they were pretty cool, so I'm gonna take a crack at something similar. Here's a book a day for November.
Might not make it to the end of the month, but I guess we'll see.
Book 1: On Magical Jewelry, by Thracius of Verditius (Communication +2, Craft: Jeweler 12, Magic Theory 10)
Craft: Jeweler Summa (Level 6, Quality 8 )
Magic Theory Tractatus (Quality 8 )
Order of Hermes Lore Tractatus (Quality 8 )
Thracius of Verditius, who died about two centuries ago, is today little remembered by the Order. But he was quite an active magus in his time, and he trained four apprentices. When he felt death approaching, he grew worried about his legacy. What if his apprentices failed to teach their own apprentices properly? His lineage would die out, and it would be as if he'd never existed at all.
So Thracius wrote this book, an illustrated guide to making and enchanting jewelry. He had a scribe copy it, and gave a copy to each of his apprentices. To this day, almost every jeweler in House Verditius has read it. Often in apprenticeship.
There are three parts to the book, which can be studied separately.
The first is the preface, a rambling diatribe explaining Thracius's life and opinions. He wrote the preface when he was too old to care about offending anyone, and as a result it's often blatantly rude. Despite that, or perhaps because of that, it contains a fair bit of interesting historical information.
The second part is a series of annotated illustrations, which explain the creation of jewelry in great detail. Thracius was a fairly skilled artist, and it's very easy to follow the step-by-step instructions he provides. This is the part that most readers actually pay attention to.
The third part is the text beneath the illustrations, which discusses how the jewelry shown can be enchanted. Most apprentices ignore this, as it's complex and often weirdly specific, but some of them return to it later in life to get Thracius's unique perspective on hermetic theory.
Huh. That ended up longer than I intended.
PS: I know there's some debate about how broad crafts should be. If you don't like Jeweler as a craft, make it something else. Goldsmith, gemcutter, whatever.
