Former military outpost of the Nethir empire and now city of over 50,000 individuals. Brassmoon is supposedly run by a Viceroy General named Ignatio Tiber but is actually controlled by a powerful thieves guild known as the Sand Net Syndicate, the leader of which is a disgustingly fat tiefling named Vipone Paramezzus. Vipone, the Vigo or captain of the Sand Net Syndicate, rules the city’s underworld with an iron fist. Despite the heavy tiefling population however the majority of the city is human and they remain extremely intolerant of non-humans, especially of gnolls (who they consider enemies of the empire) and goblins (who they think of as savages and monsters). They only tolerate such species if they succeed in the arena.
The Arena in Brassmoon is officially called the Nyos Amphitheater but is nicknamed the Garden of Blood for obvious reasons. At maximum capacity it can hold thousands of cheering fans.
The city is close enough to the Deathland Wastes that it suffers constant attacks from monsters. This gives the people a remarkable degree of paranoia and explains their hatred for so called demihuman races. The city gets most of its food from animals and farms built into caves beneath the city.
