Pencil Princess

Pencil Princess (/ˈpens(ə)l ˌprɪnˈses/) serves as the resident Rule Guru. Because ChemCraft is a game created to cater to both adults and children, the developers felt that incorporating extra familiar mediums would benefit all age groups (like characters in the style of popular/iconic games/series).

Background
Based on the style of Adventure Time's Natasha Allegri, Pencil Princess serves as a link between comforting children's television and the complicated nature of elements. By further bridging the gap and keeping things similar, one is able to focus more on learning actual chemistry (additionally, people tend to like familiar things far more than foreign ones).

Function
Pencil Princess, in her most basic form, is a visual representation of the rules of ChemQuest, and "rules" ("runs") the game guide and help forums (on ChemCraft's Wiki).
