Da Zhiti (literally, "the City"), sometimes referred to as "the Triangular Kilometre" is - or at least was until the recent collapse of global finances - Albia's economic centre, situated in the heart of Blizsta.
The historic core from which the whole of Blizsta would later grow, its borders largely follow the lines of the wall built by the Romans in the second century AD to protect what was then the city of Blisdinium.
It has always been a centre of trading(*), though today the cunning market men and women are more likely to try and sell you a double-reversed, rainbow collateralised-debt-obligation or other such financial instrument rather than a scruple of wet fish (sadly, the value of both turns out to be exactly the same). These modern-day financial whizzkids(**) are usually referred to as Zhiti-boys.
(*) and, judging by the fact it was almost wholly burned to the ground in 1212 and 1666, also a centre of insurance fraud
(**) or rather, given the current economic crisis, "grasping idiots"
