I would like to make a Dark Eldar Kabalite Warrior. She would be exiled/lone survivor from a demolished Kabal that lost favor with others amongst the Dark Kin. OOC I will not backstab or betray any of the players as that destroys the mood of the game, IC I will not backstab or betray any of the characters in the crew because that will just mean the death of the character too and sending her soul straight to Slaanesh. She ain't in any way able to negotiate any power play with anyone but is just trying to get away and the Rogue Trader is just the quickest way to do so for the time being. She wouldn't be happy sullying herself to work with Mon-Keigh, but sometimes you do things for survival and that is what it is...survival.
I would like to eventually have this Drukhari start to understand how humanity is able to function and see how adopting some of their traits would be beneficial should she gain enough power to form a Kabal again. Regardless, I would like to do this because I also want to fill-in some story for my Archon of the Kabal I'm making in the tabletop miniatures game of 40k which will be part of the Ynnari. The Ynnari are filled with what many of all factions of Eldar would deem as, extreme, or radical. So having someone who is not an 'orthodox' Drukhari and follows radical ideologies would be a fitting addition to the Ynnari in my opinion. I could be wrong, but I still want to do this and if there is a GM who is willing to help with this I will appreciate it greatly.
Due to how the setting of Rogue Trader is set before Gathering Storm I would like that to still be before that as it would help development for when the Ynnari come
