Elantris

: Track whether the "Chasm Line" has been added to determine if the magic "fires" or remains "inert" (represented by dark, oily smoke).

: Upon successful drawing, the interface could transition from "grimy and dull" (the state of the city during the Reod) to "glowing and silvery" (the city's original radiance ).

: A canvas where users draw specific shapes (Aons). The system validates the geometry against the Aon base forms found in the book's Ars Arcanum .
