Do you have any more with your Sith Warrior and his relationship with Vitiate? It seems interesting.
It's been a while since I drew him! Thanks for the ask!
Khreyn has a blind trust in his emperor, because he feels like he's the only person in the world who saw his potential when everyone else dismissed him. He trusts his emperor so much, even going so far as to deny the harm he causes around him. Valkorion, obviously, benefits from this.
Since Khreyn is rather lonely because of his traumas, Valkorion will gradually isolate Khreyn from his companions and the other Outlanders (especially Theron of course since his love for him could be a problem for Valkorion later) by telling him that his friends are not trustworthy, that they will betray him one day or another, just like everyone else before in the past, etc, etc.
All this to make sure that Valkorion would be the only person left who the Empire's Wrath values. So, when Valkorion "disappears" in chapter 12 of KOTFE, Khreyn will be all the more desperate to regain his trust, by any means necessary...
