Magic

What it governs

• The level buys accuracy and magic defence; damage comes from the spell's tier.Charter, Part II — Combat group
• Every cast uses up runes; a spell tried below its level backfires.
• No teleportation, ever: the law altar moves objects, never a body.
• Turning goods into gold waits until citizens have invented gold coins.

What it branches into

The three books. Not tiers of one ladder — three separate roads, found in different places.

• Standard: the first, found at home, with superheat for the smith.Charter, Part II — Combat group
• Ancients — the northern road, with the ice line at its deepest tier.
• Lunar: healing others, wards and sky-study, anchored to the isle in the far south.
