Stormreach itself was originally built by pirates looking for a good hiding place. Eventually it became populated by individuals from all over Eberron looking to make their fortunes on the continent of Xen'Drik, a place that holds the promise of glory, wealth and fame to the strongest survivors. While the city was supposed to feel wild and dangerous, it also had to have its opulent and civilized places where bankers, politicians and important families would feel comfortable going about their daily business. Sort of a mix between Tombstone and Paris.
