In a medieval world, nobody stood alone. Especially amongst nobles, family ties and lineage were of utmost importance. Every player in BattleMaster represents one influential family. You can have multiple characters, even up to three at the same time, but they will all always come from the same family. As in most cultures in the real world, that means they share a common family name, which makes it easier for all players to see which characters belong together. Please remember: Trying to circumvent this by registering for the game more than once is considered cheating and will be punished with the deletion of all characters of the cheater.
Families can accumulate fame and monetary wealth. Fame comes automatically from highly successful characters, while wealth is accumulated by characters giving money to their family instead of spending it in-game. Fame and wealth in turn help newly created characters, who can start the game with more prestige and initial gold.
