Ars Arcanum (Latin for "The Art of Mystery") is a glossary or appendix section at the end of the books that are part of the Cosmere universe. The information is presented from an in-universe perspective.
Every Ars Arcanum is written by Khriss. The illustrations from the various books are made by Nazh.
Ars Arcanum in each book or series
All of the cosmere stories containing an Ars Arcanum are listed here in rough chronological order.
The tenth anniversary edition of Elantris has an Ars Arcanum that lists all of the Aons and their meanings, along with a brief write-up of AonDor. Other editions do not have an Ars Arcanum.
The books in the Mistborn series each have an Ars Arcanum with the table of Metallic Arts, describing what each of the Allomantic metals does. Since more metals are discovered and new things about them are learned, the table in each later book has more metals and information with greater accuracy.
The Ars Arcanum in Warbreaker includes a table showing the abilities granted by the different Heightenings of BioChromatic Breath.
