Similar aspects- siblings, I would suppose, but opposites, one dark, the other light.

The Stark sisters are their latest find, two girls so dissimilar that you wouldn’t think they go together. Arya, so fierce she seems more animal than girl, hair scraped back like a boy’s, is all swagger in her tight dungarees and oversize leather jacket. Little, but she’s so quick with a knife that even Asha has a hard time catching her. And Sansa, schoolgirl sweet in her tight dresses and soft sweaters, except she don’t smile.
Iroas and Mogis are as different in appearance as they are in personality.
