That one may not actually make much sense unless you've read the Thomas-focused novella, actually. :/

Here, have some more: I suspect that Drou is a practitioner (after all Negri wouldn't neglect the Princess's safety on that axis either) and thus all her daughters have various levels of power. Kareen was one of the first Barrayarans of Wizard power levels to go to Beta Colony, and part of her adventures there involve liaisoning with the galactic descendant of the White Council. Martya has her own projects, and Delia is going to be invaluable to ImpSec once she's knocked enough heads around...okay tbh at this point I just want there to be a story about Dono and Olivia playing with magic, crossover canon regardless.

Harry Potter/Vorkosigan crossovers were actually how I found Vorkosigan fandom! :D Padma and Padma would be... interesting, especially since neither of them have much canon...
