Indisputable: Unknown Territories
Located in most ports with a Taxzavi population, their enclaves tend to invoke a sort of old-earth bazaar feeling, one of many cultural similarities that make interactions with humans so easy. They are often crowded, and the smell of foods and species from dozens of worlds is strong enough to render species with sensitive noses unconscious. Technically, each enclave is sovereign Taxzavi soil and therefore obeys their laws banning government oversight of mercantile interests. You can buy or sell anything here, if you know how.
