->For some of this mythical goodness, try throwing relatives of [[PlayerCharacter PCs]] into your campaigns. Imagine if the paladin finds the evil necromancer is her father. Or the grizzled space-freighter captain learns that one of the new crew recruits is the daughter he never knew about. Or two [=PCs=] discover they're half-siblings! ''The dwarf'' and the ''elf''!
