Lessee...while there are a bunch of unique cultures, that of the nation of Eyros itself is by far the most unique. It is ruled by first-generation half-orcs, which means that one parent is an orc from one of the three orcish Pillars (High Noble Houses) and one parent is a human from one of the three human Pillars. This means that the Grand Monarch's children can never ascend to the throne. The state is policed by the Praes Thanatos, a cadre of necromantic gnomes led by the all-male Patriae Sicarii, though a new generation of half-dryad gnome females is rising, perhaps to challenge the patriarchy, due to the influence of the Bloodwillow dryad Sania. The country is protected by Elven Masks, wizard-slaves who are kept servile and with the mind of a child by magic, but they live for much longer even than normal elves. Meanwhile, a hidden faction of dwarven psions tries to fight for their political freedom and the halflings have escaped Eyrian hegemony altogether by turning to the sea, living on floating cities and practising piracy----and that's just the beginning!
