An answer to the the question of what Leia could've looked like if she had embraced the darker side of her heritage.

Main trigger is sith_leia and other triggers that help are abs, cleavage and braided ponytail. Holding a lightsaber adds a lightdagger in PONY.

Illustrious doesn't seem to like daggers, so it may take more effort to get dagger length lightsaber. Try adding dagger and lightsaber dagger in prompt, it might work.
