Heroist

Sorry, I seem to be stuck on the clue about the witch. Anyway, I've concluded that the connection between Turkmenistan and a specific district is very weak and unlikely, so I started searching through landmarks in larger regions of the country, but I couldn't find anything. Either the connection goes further through a country-to-country link, in which case guessing is pointless, or there's some kind of clever associative connection.
Whatever
