Temira "Tea" Kartal, also known as Stardust was hot-headed, tough and pretty much a rock to your head. In other words a nightmare if you cought her on a bad day, as quite a few people has experienced. She started out on the wrong foot with Dairen, as she mistook him for a proper demon and wanted him executed. Not that Dairen got angry over it, rather terrified of Tea's bad temper. Her work name is Stardust but as she is an adult woman she prefers Tea over "silly code names" (I can understand her).
From TEMIR: Kazakh form of Temür; meaning "iron".
