Talis is one hell of a city. It is both a bustling metropolis and the edge of the civilisation, home to millions of humans and faerie, and the centre of trade and magic. Ruled by a benevolent, but firmly entrenched, duke, Talis has a history dating back thousands of years, including centuries under the oppression of Witches.
Talis is also packed with stories. The Witches were overthrown by a human/faerie alliance - an alliance that has since dissolved. The faeries are second-class citizens in the city. They live packed into a ghetto, the population of which increases daily with refugees from the surrounding wilderness. Others have assimilated into human society, trying to fit in as merchants, artists or political power-brokers. On the human 'side', the Duke has no heir, and the city's many aristocrats and nouveau riche jockey for position - while the Emperor looks on, impassively, from afar. The city guard is rife with corruption and intrigue, but still stands as the last line between the city and total anarchy. Talis is the proverbial powder keg, with strangers, politicians, rebels, wizards, and detectives all running around with matches.
Appropriately enough, Irons in the Fire begins with an explosion.
