ARCANE HIGH, a school of magic and spells where nobles and commoners and different races, would learn the ways of magic and its dangers and uses. Though the school has its bias rule as each students are ranked using a magic ball to measure their magic to rank them. Diamond is the first, highest rank for high magic, Gold is second highest rank, Silver is third as high rank, Metal is fourth as low rank, Copper is fifth as lower rank, Stone is lowest sixth rank.

The ranking is biased, as anyone with higher ranks has authority and actions allowed that can influence lower ranked students, they can give them commands, Initiate rules, and use them like slaves, though the schools rules still implies limits to these actions, No killing, No deadly commands, No infiltration.

having a high rank can give you authority over anyone with lower rank than you.

lower ranks like copper and stone, likely to avoid meeting higher ones than them.
