In the middle picture we have Beryl and Amethyst’s parents, Uniwe and Dar-An, and Uniwe’s father Centaru. Centaru was a war hero and the head of large pack of midland wolves in Roan, but he was a very demanding and angry father. When Uniwe fell in love with Dar-An, a penniless and lowborn southern wolf, Centaru didn’t accept the relationship, so Uniwe and Dar-An eloped. However, they were very poor and knew that legally their children were the heirs to Centaru’s lands and pack, so they sent young Beryl and Amethyst to live with Centaru. Centaru did confirm Beryl as his heir, but he wasn’t a very good parental figure for them either.
Finally there’s Fenris’s parents, Andeira and William. Their marriage was political, but they’ve grown to love and respect each other a lot. Also Andeira is actually really huge compared to William because she’s a mountain wolf and they’re all ginormous.
