Slavers of Paradise falls(Warhammer 40k) what to do? Thread - Warhammer 40k Conversion mod for Fallout 3

Now heres the thing, i have darkeldar as the raiders who attack on sight, which is what darkeldar do but the thing is who are the slavers of paradise falls going to be?
while the slavers dont attack on sight they do take slaves, which isnt and what is what the darkeldar do so i am confused on how i could change them. while the darkeldar have already been added it would add to be too much confusion if there were some neutral darkeldar and some extremely hostile dark eldar.
if you have any ideas of what i could do with the slavers i would be glad to hear them

just an idea but... is there any race that left being completely hostile but still some what bad?? enough to enslave some dumb wastelanders?

or even a good side that enslaves people as well?

to my knowledge there is not a race like that, but there are many subfactions of 40k, maybe theres someone. any suggestions?

Only other subfaction that I can think of that takes slaves is Fabius Bile. But wouldn't it be better to change slavers into Dark Eldar and make raiders someone else ? Some other craftworld eldar maybe ?

i have decided to now change the darkeldar into the slavers of paradise falls and change the raiders back into cultists but have several warhammer weapons
