Famous Oognook family name.
From northernmost Aelioanei, the Aats were some of the most influential of the native people. They have existed in those islands since before recorded time, and their early exploits are still told by the oral historians that keep the traditions alive. Their most important contribution to their people was the institution of public schools, which saw the Aelioanean Islands reach high levels of culture long before the first refugees from Proterse started to arrive after the Ha Wars.
Dina Falls, Arianna Falls's mother, was born Dina Aat. She was encouraged from a young age to take on the family interest in education, which she did out of obligation to her ancestors. Apart from her award-winning career, Dina Falls was a member of the Protectorate just before the birth of her first child, Brit Falls, and made the decision to entrust Aislin's pieces of the Book of Knowledge to Slate Ahn.
