This massive tome is bound in midnight-blue hide shot through with veins of translucent crystal. Its covers bear a many-pointed circle in gold, surrounding a crystalline feather that shifts like a living star. Inside, diagrams rearrange themselves as the reader studies them. Some pages hold precise formulae; others preserve smudged drafts, crossed-out experiments, and faint impressions left by earlier students. When a circle is formed nearby, the book opens and its pages turn toward the participants.
Lore
On the first page, in Cygnus's hand, is written: “I discovered the circle alone. I do not intend for it to remain that way.” The Codex is a teaching tool and a shared record of magical inquiry, not merely a weapon. Its pages gather the understanding of its readers, turning each new circle into part of a lineage of study.
History
After years of developing Circle Magic alone, Cygnus began compiling his discoveries into a tome that could teach the discipline rather than merely describe its results. He enchanted its pages with his own craft and magic drawn from crystal beasts, allowing them to remember traces of each practitioner's work. The Codex preserves not only successful techniques but also failures and revisions, so future mages can build on the experience of those who came before.
