• Traditionally, they are given middle names representing some virtue. These names used to be very on the nose, such as Kindness and Peace. But the siblings' parents, though traditional, are also sensible, so the siblings have more normal-sounding virtue-based names.
• Since only blood members of Families can be bound to skins, only one of the siblings' parents can be skinbound - to avoid making the family tree a wreath, as Meander so succinctly put it.
• The skin that accepts Mara (Actaeon's Mantle) actually initially rejected Auri.
• Falling in line with the communal nature of the Whitethorns, the siblings' parents have a very equal relationship. No patriarchy here.
• The Whitethorn property is fairly northern, so it gets cold and snowy in the winters. This is one major reason behind the skins all being fairly warmly made (Auri's fur mantle, Daria's gloves, etc).
• The Whitethorn property hosts a great coniferous forest which is home to many animals, but does not welcome bears, wolves, or snakes. The reason for this is fairly lost to time (the original rule was a political statement!)
• The Whitethorn manor itself is quite large and beautiful. The parts that are open to visitors and guests are bright and gilded, but the parts that are lived in and commonly used by the family and servants are warm and cozy. These parts of the home are made of darker wood and host many stained-glass windows that serve as ancient murals depicting historical predator-prey relationships. The rooms are carpeted and insulated to keep residents warm in the winter.
• The family has several heirloom deerskin blankets that see constant use in colder months; as Meander said, not only are family members being warmed by the blankets, but by their Line.
• The family also has multiple horses, which they drape with extra deer skins in the winter both to keep the horses warm and as a political statement to show their allegiance when out riding.

Reverie is lovely too <3
