These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Ixia and Sitia
Nightmare Fuel: Yelena and Opal have some pretty awful dreams about their past experiences.
Purity Sue / God-Mode Sue: 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.
