Where the facts come from

Roshar is verified against the Stormlight Handbook, chapters one to seven. Scadrial is verified against the official Mistborn Player Quick Reference, GM Rules Overview and Metalborn sheets, plus the twelve pregenerated characters of Hope in Ashes and Engines and Espionage.

Those twelve pregens are also what pins the shared maths — health, defences, and the attribute bands for movement, recovery, senses and lifting — because they show the same formulas at two different levels.

Every claim inside the Wayfinder carries two tags: what kind of thing it is, and how well sourced it is. Anything still reading community, unverified is genuinely unconfirmed — chiefly which level each Rosharan talent unlocks at, which the Handbook lists alphabetically rather than by tier.

Names, costs and numbers are reproduced as reference. Rules text is not. These are planning aids, not a substitute for the books.
