One of my favorite characters of all time, the Romulan Commander from The Enterprise Incident.  TOS,   she whispered her name to Spock, which he found rare and beautiful.  In fan fiction, her name was revealed as  Liviana Charvanek, which is kind of pretty.  She just oozed cool, didn’t she?  From artist anotherminerva on DeviantArt.   Nice, I like that the artist added green lips!
