One of my favorite Star Trek characters is Garek the tailor (heh) from DS9. Another topic got me thinking about him, and to a lesser extent DS9, and it occurred to me . . . DS9, like Babylon 5, should have a lot of character types we would see in the main city of worlds like Galatea, Solaris VII, Outreach, Herotitus, Antallos, and Tortuga. To a lesser extent we might see them on worlds like Arc Royal, Nosiel, Northwind, Astrokasy, Westerhande, Fletcher, Oberon, and other minor merc/pirate worlds.
Unlike DS9's Garak, a BT version would be harder to pin with connections to a Great House intel operation- but what one in your opinion might be best for imitating the link to the Obsidian Order? Garak was (supposedly) involved in spying, assassination, COIN and interrogation as a operative before his exile. What other character traits/behaviors might carry over from the DS9 version?
