Codex Incabulum

The page under the opening flap, which is bound in a leathered skin, stitched and stapled together with small teeth coming out near the opening, opens to a page written in common simple reading 'Codex Incabulum' under which in smaller text is written 'Silas.' The book bounces back and forth between being written in common, Abysal, Infernal, and in very old runes. Some pages are dedicated entirely to pictures or large scale mock-ups of summoning circles and diagrams. The book is incredibly heft, weighing at least 10 lbs. It smells oddly of sulfur when held close to the face.

Attunement to a codex requires 8 hours of uninterrupted study 6 days a week for a month.
