In a world where everyone gains access to a generic class at 18 years of age on entering their first dungeon, some are born more equal than others. The five great houses, two dukedoms, two marquisates and the royal family, each have access to their own private dungeons accessible only to to their bloodline and only once in their lifetime. These dungeons do not grant the generic classes but rather customised classes tailored to each individual. Charles is the last of his line after the mad king Regnar Plymouth IV toppled all but one of the other great houses in order to consolidate his rule. His father was betrayed and murdered, his Duchy stolen and he was kept as a political prisoner till the day he turns eighteen. Tomorrow is that day. Will he become a puppet for the mad king or will he find a way to strike back and retake his inheritance?
