Kasari Adaar
A two-handed-weapon Reaver and rather posh stoic, she tends to confuse people with her preference for Tevinter-inspired aesthetic. She's quite protective of her family, especially given the age difference and the fact that both her siblings are mages; she was heavily injured protecting them from Templars when they were children, and doesn't have a very high opinion of the Chantry as a result. The first to join the Valo-Kas to support the Adaar family, she was with Shokrakar when the Conclave exploded - and very hastily made her way to Haven to try and find her sister, whereupon she refused to leave without her.
Joining the Inquisition is not what she would have preferred, but maybe things aren't all bad... Lady Josephine is quite... enchanting.
Kiva Adaar
Having grown up quite sickly, she's been rather (overly, in her opinion) protected for the sake of her health - though not naïve, she prefers to believe the best in others, and gets excited about new experiences. She'd been with the Valo-Kas not even a year before the events of the Conclave. Waking up with her hand glowing green was pretty alarming... but maybe it could end up being a great adventure, too!
Her enthusiasm for learning about and utilizing the power of the rifts might be a little unnerving (even for Solas), but high risk, high reward!
Ankir Adaar
He is the baby and his sisters will never let him forget it. Having been at home with their parents during the Conclave, he's not really even known to the Inquisition until the rest of the family arrives to the safety of Skyhold - and with Kiva and Sari making names for themselves, he cannot wait until it'll finally be his turn.
The way of the Shapeshifter appeals most to him, and he ends up under the tutelage of Lady Amell - much as he's very anxious about being taught by the Hero of Ferelden (!!!).
(Kasari and Ankir are both @thatferrybroad creations; in her own canon, Sari is Inquisitor. I also forgot that they both have dark sclera, so now Kiva gets it too, lol)
