Veil

For Veil, I definitely see more of Sherlock in her, color-wise and just the general vibe she gives off. After Pavo's failure to produce viable heirs, she neglected to give him a second chance and decided to have a new heir for herself - and most males in the clan are too young or non-magical. So, aiming to keep at least somewhat pure, she makes do with another House Solaris member: Sherlock.

She's unsure to have him rise in the ranks as emperor, so she doesn't marry him (and kind of goes against her own code) and ruled alone with her new daughter. She was prepping her strenuously to become the next empress - do you have anything to go from there? Sherlock probably had little involvement from her life due to Lumi's constant pushing him away, but when he was with his daughter, he probably tried to get her into smarts and astrology.
