* NightmareFuel: Yelena and Opal have some pretty awful dreams about their past experiences.
* PuritySue / GodModeSue: Yelena, more so as the series goes on. Beautiful and intelligent; Valek, who apparently 'never took interest in a woman before' falls for her; Cahil was interested in her; she's a powerful Soulfinder and also the only one in all of Sitia or Ixia; raped and abused when she was younger... the list goes on.
