I drew what I think the Inquisitors would have looked like back when they were Jedi!

-Crow feels like a Kaleesh, given his body type, claws, and face shape + mask (high-set eyes means he likely isn't humanoid and this is a distinctive feature of the Kaleesh, and the mask leaves perfect space for his tusks). The mask is definitely reminiscent of traditional Kaleeshi ones, though it's more Imperial/mechanical in vibes rather than tribal/boney. I initially drew him with a similar cloak to his imperial one, but removed it because I wanted to show the robes underneath better.

-I imagine Marrok as a Kage, given his unusual propensity for unarmed combat and attacks; their species is famous for their hand-to-hand skills. I picture him as also having been 100% locked in as a Jedi, though perhaps with some kindness beneath the irritable surface that's since been extinguished by Imperial torture. Their species canonically maintains their memories their entire lives rather than forgetting anything unimportant like humans, which could also have helped him rise to the level of prowess we see him at.

-The Seventh Sister (awooga) seems like she would have been a sweetheart before the Empire tortured her and turned that compassion into sadism. I have a headcanon that her padawan was a Quarren given her helmet shape; she seems to have always wanted to be a mother and I imagine she was very attached to her padawan, given that's the closest thing to a child a Jedi is allowed to have. The Empire would never do anything to said padawan! Never!
