Spellbook of the Leybreaker

A spellbook bound in pale leather, its pages interleaved with thin sheets of clear crystal that catch the light. Notations are written in a precise, slanted hand — the same handwriting appears in margins across multiple sections, suggesting one author over years.

Contents

Spellbook, uncommon

• Contains 4d6 random wizard spells (roll on first inspection; subsequent inspection yields the same spells).
• Contains a substantial section on leyline manipulation — theoretical notes, field diagrams, and a procedure for using crystal foci to “tap” raw ley energy without tripping the standard druidic detection wards.
• A wizard with proficiency in Arcana can copy any spell from the book into their own spellbook by the standard rules.

Notes on Leyline Manipulation

The leybreaker section is the genuinely valuable part of the book. Excerpts:

• “The line is not a wire. It is a tendon. It will tear before it overloads. Tap, do not pull.”
• “Druidic detection assumes consent of the line. Crystal foci masquerade as the line itself; the wards do not see a thief, they see the line speaking to itself.”
• “At thin places — Phandalin, Stonehell, the Frame — the line does not need to be tapped. It bleeds.”

The author’s identity is not given. The handwriting does not match the Slanted Circle Mage’s grimoire. A second hand — possibly senior to the Mage himself — was teaching this material to the Shardcasters.

Value

Approximately 300 gp to the right buyer for the spells alone. The leyline section is unpriced — its strategic value to the Emerald Enclave or to House Cannith is significantly higher than its market value, and either faction would likely pay or owe for it.
