Bazaar of the Bizarre: Floating Markets, mostly, especially those where a relativist clipper or lugger turns up. Agglomerate enough free traders together, and you get a market where you can find anything, or if not anything, someone who probably can tell you where to find anything. Including most of the things you might expect to find at thieves’ markets, smugglers’ markets, and goblin markets, not to mention those peculiar markets you only visit in your dreams.
Some other well-known markets can be like this: Glorious Acquisition Plaza on Baranithil Station, the Gyre of Commerce in Mer Covales, Seranth, and the Little Market in Calmiríë itself come the closest. But still – for the most bizarre in your bazaar, head to the floating markets.
