: 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 .

: 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 ).

: Since AonDor's power is tied to the physical land of Arelon, the feature could include a "Chasm Line" toggle. Activating it would "repair" broken Aons, reflecting the climax of the novel where Prince Raoden restores the city's magic.
