Class structure
There are two partially separate class structures: general and contractual.
General Class
A fairly standard class structure, with royals on the top and peasants on the bottom. It is important to note that merchants are around middle class, while artisans are usually higher. The majority of the population farms, mines, or does other similar work, and would be considered lower class or working class.
Contractual Class
There is an initial dichotomy: those under contract and those not, with those under contract almost always being put above those with a similar general class and no contract. From there, however, it tends to depend based on the contract itself. Those with popular roles have a higher class than those with obscure ones, and those with heroic roles tend to be higher-class than those with villainous ones.
This also ties in to contract-based celebrity.
Ever After High
Generally, the school accepts students regardless of general class as long as they are planned to be under contract, but tends to only accept non-contracted students if they are royals (e.g. Red Charming). They also give priority to royals and other popular roles when it comes to resources or housing.
