Ok, one more drawing before the night ends.
Probably gonna color this later. I've talked about them a couple times, but here are the designs for the Dark!Origins versions of the main trio, or basically who they'd be in the UNDERFELL AU.
By the time the three would meet, Ferris would already have a fair grip on her magic and be a LV. 2 while Castellar would be a LV. 5 due to the world being more dangerous and monsters and humans more likely to FIGHT even before the war. Ciara would have gained LV too, but Ferris RESETS to keep any blood off of her hands, so she doesn't even remember.
Ferris would take up stealing to keep herself and Ciara alive, and often would get them both into all kinds of messes as a result. She would've already have been killed multiple times due to not being overly strong, but would luckily have her magic to fall back on. She wouldn't be afraid to FIGHT if she felt she had to either. Although like her original counterpart, she also chose to dress less feminine and has some confidence issues, Dark!Ferris is more boastful and really plays on the tough act as a means of surviving.
Ciara would be cared for and spoiled by Ferris, but unlike her original counterpart, she'd fall into a quiet, almost bored/despondent persona. She'd know her sister was going through some heavy stuff, but Ferris absolutely wouldn't let her get involved. Even if she tried to "teach" her how to survive, she wouldn't actually give her the chance to hone her skills for fear of her getting hurt. So Dark!Ciara would just be kind of blank, feeling like alot of things were out of her control and wanting to help.
Then there's Castellar, who'd be next to nothing like his original counterpart. The sweet boy would be gone and replaced by someone who takes the well known saying of "kill or be killed" to heart. His family would've raised his to FIGHT first and the Arnaud Mage's Guild would train him as partly an assassin. And for one of his assignments... he'd have to go after Ferris. Either he'd need to convince her to join the Guild or FIGHT her until her DETERMINATION wore down to such an extreme that her power to RESET was shattered and she could inevitably be killed.
Things don't go the way anyone planned.
